Timeline of Apple’s Online Services

[I’d like people’s help in completing a timeline of Apple’s online services.]

[Update: deleted the WordPress shortcode, which seems not to be working.]

As kind of a followup to yesterday’s post about some early rumours and speculations about the iPhone, I thought about posting some info about Apple’s online services. Part of the reason is that Asymco’s Horace Dediu has frequently talked about what we could call “Apple’s data play”, for instance in this post about the iCloud data centre in North Carolina. I was also thinking about Mike Davidson’s comments about Apple’s presence (and “dominance”) in such diverse fields as hardware, software, licensing, and commerce. The trigger for this post, though, was from this Steve Jobs comment, which appeared in a recent NYT piece about the Apple Maps fiasco:

The MobileMe launch clearly demonstrates that we have more to learn about Internet services

The overall context for this quote as well as a number of discussions about Apple is the consensus that Apple does a poor job with online services. MobileMe and iTunes Ping are often used in these discussions and it seems clear to most people (including Apple executives and insiders, it sounds like) that the “computer company turned consumer electronics vendor” has a lot to learn about online services.

The reason I find this so interesting is that Apple seems insistent on pushing at least some of its online services. A bit less of a “betting the farm” strategy as Google’s “Emerald Sea” initiative, but an intriguing strategy for such a large and still-successful company. Dediu’s frequent reference to Clay Christensen’s concept of “Disruptive Innovation” might apply, here. Apple might be “disrupting itself into” an online services company, at least in part.

There are several things I find intriguing about this strategy.

As opposed to most other enterprises’ “online plays”, Apple’s model tends not to be based on ad revenues. The divide between Google and Apple couldn’t be stronger when we talk about ad-supported free/freemium services as opposed to paid services or services attached to other purposes. It’s likely an irreconcilable difference between fans of  both teams.

Online services are clearly not Apple’s strong suit. It often sounds like Apple is missing a “magic touch” with online services, the same way other companies are said to lack Apple’s design sense. This is more similar to Google+ given the consensus that “Google doesn’t know how to do ‘social’”. But it’s still surprising.

Though Apple may not have a “knack” for online services, it’s been trying to do it for quite a while. I keep thinking about eWorld as a precursor to the whole thing. It’s one thing for a company to try its hand at something new or to pivot into a strong business. It’s another thing entirely to shift more energies into something which has so far proven to be mostly a lost cause.

Adding to my thoughts on this was a podcast conversation (I think between John Siracusa and Dan Benjamin, though it might have been between Marco Arment and John Gruber) during which comments were made about those Apple employees working on online services.

So, basically, Apple’s online services have been on my mind. But I couldn’t find an exhaustive list. Tried Wikipedia but it doesn’t really separate online services from other things Apple does. And I ended up thinking about what would define “online services” in Apple’s case. Everything Apple does which incurs some bandwidth costs would be my working definition. Basically, it’s something to do with Apple investing in data centres and such. Some of these seem like very small costs (hosting data about podcasts, instead of the podcasts themselves, for instance). Given Apple’s size, these costs and the infrastructure behind all of this can be quite big.

So I started listing some of these services and organizing them in a sort of timeline, first in MultiMarkdown format in nvAlt, then in a Google Spreadsheet. I then discovered Vérité.CO’s Timeline.JS which takes a Google Spreadsheet and makes it into a visual timeline.

A few notes:

  • It’s a quick draft and I didn’t really check any of the data points.
  • In most cases, I only added months and, in the case of “AppleLink”, I only put years.
  • I took most dates from diverse Wikipedia pages, not necessarily backtracking on the whole process.
  • On at least one occasion, there was a discrepancy between two dates.
  • Sometimes, I took the date of the service’s announcement while I used an actual launch date for other services.
  • I only added a couple of pictures to show that it can be done. Many of the relevant pix are likely to be under copyright or to constitute a trademark.
  • I tried to be as exhaustive as I could be, but I’m sure I forgot stuff.
  • Some things may not sound like they qualify as part of “Apple’s online offering” but I think they’re still relevant. My rule of thumb is that if it goes to Apple’s servers, it’s an online service.
  • I separated some services from “suites” like iCloud or iTools, partly because some of those services haven’t been kept, which is important to see in a timeline. There are several services missing, here.
  • None of this timeline is meant to be editorial. I was just curious about what Apple has been doing online since the 1980s. The reason I care can be found in my earlier notes. I consider myself neither an “Apple fanboi” nor an “Apple hater”. I just find the situation revealing of something happening in the tech world, which has an impact on the Geek Niche.

So, here goes.

Here’s the Google Spreadsheet (editable by anyone):

Apps and iTunes Cards in Canada: Follow Up

Recently blogged about this issue: though information about this appears nowhere on the card or in the terms of service, iTunes Cards (gift cards or certificates) may not be used to purchase applications on the Canadian version of the iTunes Store.

Since I posted that blog entry, a few things have happened. I did receive replies from Apple, which were rather unhelpful. The most useful one was this message:

Hello Alexandre,

I understand and apologize about your situation and i do want to assist you as much as possible . I am going to issue you 10 song credit. Again i apologize and i hope this issue gets resolved. I will also apply feedback about this issue .

Thank you for choosing iTunes Store and have a great day.

Sincerely,

Todd
iTunes Store Customer Support

I had no intention of purchasing tracks on the iTunes Store at this point but I do “appreciate the gesture.” Here’s what I wrote back:

Thanks. I wasn’t planning on downloading songs but I appreciate the gesture.

Not overwhelming gratitude on my part. Simply stating that, though this isn’t appropriate, I can still be polite.

What’s funny is that I received this reply to my simple “thank you” note:

Dear Alexandre,

You’re very welcome. I’m glad to hear that i was able to help some .

Nothing makes Apple happier than to hear that we have pleased our customers. I hope that you continue to enjoy the iTunes Store.

Thank you for choosing iTunes Store and have a great day.

Sincerely,

Todd
iTunes Store Customer Support

From that message, you’d think I had praised the iTunes Store for hours on end.

Just in case it might make a difference, I tried filing another support request. Here’s the reply on that one:

Dear Alexandre,

Welcome to the iTunes Support Site. My name is Staci and I am here to assist you.

Thank you for contacting Apple about the App Store. We’re glad you’re interested in
this new offering.

I’m sorry, but you will not be able to purchase games or applications with store
credit or an iTunes Gift Card in Canada. Customers residing in Canada may only
purchase games and applications using a credit card.

I am confident that the information provided will solve your gift card issue. If
you have further questions, I can be contacted during the hours listed below. Thank
you and have a prosperous New Year.

Sincerely,

Staci
iTunes Stores Customer Support

This one sounds even more like a canned reply and  “the information provided” doesn’t, in fact, “solve [my] gift card issue.”

Clearly, Apple isn’t “doing the right thing.” In terms of customer service, it’s not a positive experience. I did enjoy some aspects of the iTunes Store and I think it’s quite convenient. But I’m not “enjoying the iTunes Store” so much, anymore.

In the meantime, I started receiving comments on my previous blogpost on the issue. One was from someone who purchased a 150$ iTunes Card. Almost as much as the 8GB iPod nano.

Most of the advice given on this issue, outside from Apple’s unhelpful replies, has to do with things which are illicit. One would be to resell tracks purchased with this card to other iTunes users. Since the tracks are now all DRM-free, this is technically feasible. But it’s also illicit and potentially traceable. Another piece of advice, to purchase applications using an iTunes Card, is to buy a card in the US. As far as I know, this is technically doable but it also contradicts Apple terms of service.

Not good solutions, but ones which disgruntled iTunes Card buyers may contemplate.

Since then, I also received a message asking me to complete a survey about my experience with Apple support. Here’s the complaint I included in that survey:

I was given the “runaround” on a very easy issue: I need a refund.
There’s an obvious problem with the fact that iTunes Cards may not be used to purchase applications on the Canadian version of the iTunes Store. Nowhere on the card itself or even in the Terms of Service is this restriction mentioned. As this issue gains prominence, Apple could get a significant hit in consumer perception. Not sure if it will become a class action lawsuit, but it’s as significant an issue.
Email replies were disappointingly unhelpful. Instead of investigating the situation, I was led to a forum post musing about the possible reasons for this restriction. I was eventually credited ten songs even though I had no intention of getting tracks on the iTunes Store at this point.
While the amount of money is relatively small in my case, I’m getting comments on my blog from people who lost the money equivalent of an iPod nano.

Again, I probably won’t file a class action lawsuit against Apple, in part because these suits mostly make money for lawyers. But my dissatisfaction with Apple remains. In a way, it even grows, because there were several opportunities for Apple to “do the right thing.” Yes, it’s partly on principle. But it’s also a matter of the way the corporation is perceived. In this case, they sound polite but quite dismissive.

There’s no question in my mind that a mistake was made: no information on this restriction was added anywhere a gift card purchaser may find it. Because of this, people are redeeming iTunes Cards with the specific intention of enjoying their iPhone or iPod touch in a new way. As this was a season of gift-giving, some people probably received these gift cards and, thinking they might use them anywhere on iTunes, redeemed these cards instead of returning them. Only to find out, after the fact, that “you will not be able to purchase games or applications with store credit or an iTunes Gift Card in Canada.”

Bummer.

This frustration isn’t such a big deal in the abstract. But context is everything. Part of the context is the set of restrictions placed by the iTunes Store in general. It may not have been much of an issue, for a given user, that it’s impossible to buy applications directly from developers, unlike Android Market (the Google equivalent to the App Store). For casual users, this is pretty much a non-issue, especially since the App Store is so convenient. But this restriction becomes quite conspicuous once an iPhone or iPod touch user runs into this kind of problem.

There’s a broader issue. With the iTunes Store, Apple is sometimes said to have “solved micropayment.” Ever since the iTunes Music Store opened, at least part of Apple’s success has been assigned to the Amazon-like way they implemented their payment structure and it’s quite likely that the iTunes Store model has been having positive effects on the way Apple is perceived by investors. Because of the way it handles payments and reduces overhead, Apple has been able to make money on relatively small amounts of 99¢ (and, recently, 69¢). I’d call this “minipayment” because one can easily imagine even smaller amounts being paid online (for instance, a minute of cellular or long-distance communication). In this case, Nokia, eBay/Skype, and cellphone carriers have better micropayment systems. But Apple still deserves “Wall Street cred” for the way it handles small payments.

Yet, once you start thinking about Apple’s payment system in more details, say because of a bad experience with the applications section of the iTunes Store, you start noticing how flimsy the payment structure is because it relies on users willingly entering a closed system. It’s not just that the iTunes Store is closed. It’s that, once you buy on Apple, you need to restrict yourself to “Apple’s ecosystem.” This has often been the case on a technical level. It’s now a matter more visible to the casual end user: money.

From a “tech media” perspective, this closed ecosystem is part of a pattern for Apple. But the financial part isn’t frequently discussed.

It will sound like a strange analogy but it’s the one with which I come up as I think about this: IKEA bedding. Because IKEA’s measurements are metric, bed linen was an issue with IKEA-purchased mattresses in Canada. Not sure if it’s still the case but it used to be that those who bought beds at IKEA were then stuck with metric measurements for bed linen and those are difficult to find in Canada. In effect, those who purchased beds at IKEA were restricted to IKEA linen.

In computer terms, the classic case is that of a difference in fileformat between products from two developers. Apple certainly had its share of “format wars” but it mostly solved these issues. Recent Macs (including the Mac mini Intel Core Duo I’m currently using) support a Windows installation as well as Mac OS X. In terms of networking, it’s now quite easy to set up mixed networks with both Mac OS X and Windows machines. Even the music part of the iTunes Store is lifting those restrictions which made them technically incompatible with other devices. All in all, Apple has gone away from its strict control, at least in technical terms.

But in financial terms, Apple is using a fairly restrictive model for its iTunes Store. Once money gets into an account (through gift cards, allowances, or “gifting”), it can only be used on that account. Because of some restrictions specific to Canada, some of that money is restricted from use for buying applications. And Paypal isn’t available as a payment option in the Canadian iTunes Store. In effect, the only way to purchase an application for the iPhone or iPod touch is through a valid credit card. Given the fact that a majority of people are likely to have some kind of credit card, this doesn’t seem too restrictive. But there’s a variety of reasons people may not have valid credit cards and there’s no connection between buying something on the App Store and using a credit card. The iPod touch has been marketed as a gaming platform during the holidays and chances are that some iPod touch owners are children without credit cards. I’m not sure what the options are for them to buy iPod touch games. The same could be said about games for the iPod Classic, a device which clearly is used by children.

Part of the problem relates to the Canadian financial system. For one thing, debit cards with credit card numbers are rare in Canada (I’m not sure they exist). Many Canadians tend to use Interac, which does offer some advantages over credit cards, IMHO. As I’ve recently experienced, Interac now works online. It would make a lot of sense for Apple to support it online (I’m sure Canadian Apple Stores already support it). And there must be a reason Paypal, which can be used for iTunes Store purchases in the US, is unavailable in the Canadian iTunes Store.

So, yet again, Apple’s Canadian customers appear “underprivileged” by comparison with US customers. In public perception, this is pretty much a pattern for Apple.

I don’t think that the messages I’ve received helped. Though they were polite, they were dismissive as my problem was basically dismissed. From being dismissive, Apple can sound arrogant. And arrogance is tricky, in today’s marketplace.

I’m reminded of the recent Simpsons episode about Apple. Excerpts of it made their way to YouTube as they play on several gripes people have with Apple. Arrogance was clearly a key theme in that episode. Another Apple parody, the MacBook Wheel spoof from The Onion, was more directly centred on making fun of users and elements related to Apple’s perceived arrogance were less obvious.

I don’t own AAPL.0 stock but, if I did, I might sell some. Sounds silly but corporations which treats its customers in this way aren’t something I would invest in. Despite the fact that I do “invest” in Apple products.

I just wish Apple “did the right thing.”

iTunes Gift Card on Canadian App Store? (Updated)

GRRR! :-E

Disappointed by an iTunes gift card

Disappointed by an iTunes gift card

 

[Update, December 27 8:55 pm: I received a reply from Apple:

Dear Alexandre,

Hello my name is Todd and i am happy to assist you. I understand that you would like a refund for your gift card that you purchased without knowing that you couldn’t purchase applications unfortunately i am unable to approve a refund because once a Gift Card has been redeemed, it no longer has any value. The store credit on the card has been completely transferred to the account it was redeemed to. I did some research and i came across this link where apple customers go and send feedback about issues they have experienced and I think you may find this informative.

http://discussions.apple.com/thread.jspa?threadID=1780613

Thank you Alexandre for choosing iTunes Store and have a great day.

Sincerely,

Todd
iTunes Store Customer Support

please note: I work Thursday – Monday 7AM – 4PM CST

So it seems that the restriction is due to Canadian law. Which makes it even more surprising that none of the documentation available to users in the process of redeeming the code contains no mention of this restriction. I find Apple’s lack of attention to this issue a tad bit more troubling in context.]

I’m usually rather levelheaded and I don’t get angry that easily.

Apparently, iTunes gift cards can’t be used on the App Store portion of the Canadian version of the iTunes store. It seems that, in the US, gift cards can in fact be used on the App Store.

This is quite disappointing.

Because of diverse international moves, I currently don’t have access to a valid credit card in my own name. During this time, I’ve noticed a few applications on the iTunes App Store that I would like to purchase but, since I didn’t have a credit card, I couldn’t purchase them. I do have a Canadian Paypal account but the Canadian iTunes doesn’t accept Paypal payments (while the US version of iTunes does). I thought that Paypal was able to provide temporary credit card numbers but it seems that I was mistaken.

So I thought about using an iTunes gift card.

And I started thinking about this as a gift to myself. Not exactly a reward for good behaviour but a “feel good” purchase. I don’t tend to be that much into consumerism but I thought an iTunes gift card would make sense.

So, today, I went to purchase an iTunes gift card for use on the App Store portion of the iTunes Store.

I felt quite good about it. The weather today is bad enough that we are advised to stay home unless necessary. There’s ice all over and the sidewalks are extremely slippery. But I felt good about going to a store to purchase an iTunes gift card. In a way, I was “earning” this card. Exercising a lot of caution, I went to a pharmacy which, I thought, would sell iTunes gift cards. I know that Jean Coutu sells them. Turns out that this smaller pharmacy doesn’t. So I was told to go to a «dépanneur» (convenience store) a bit further, which did have iTunes gift cards. Had I known, I would probably have gone to another convenience store: Laval, like other places in Quebec, has dépanneurs everywhere. Still, since that dépanneur was rather close and is one of the bigger ones in the neighbourhood, I thought I’d go to that one.

And I did find iTunes gift cards. Problem is, the only ones they had were 25$. I would have preferred a 15$ card since I only need a few dollars for the main purchase I want to make on the iTunes App Store. But, given the context, I thought I’d buy the 25$ card. This is pretty much as close as I can get to an “upsell” and I thought about it before doing it. It’s not an impulse purchase since I’ve been planning to get an iTunes gift card for weeks, if not months. But it’s more money than I thought I would spend on iTunes, for a while.

Coming back home, I felt quite good. Not exactly giddy, but I got something close to a slight “consumption rush.” I so irregularly do purchases like these that it was a unique occasion to partake into consumer culture.

As I was doing all this, I was listening to the latest episode of The Word Nerds which is about currency (both linguistic and monetary). It was very difficult to walk but it all felt quite fun. I wasn’t simply running an errand, I was being self-indulgent.

In fact, I went to get French fries at a local greasy spoon, known for its fries. It may be an extreme overstatement but a commenter on Google Maps calls this place “Best Restaurant in North America.” The place was built, very close to my childhood home, the year I was born. It was rebuilt during the year and now looks like a typical Quebec greasy spoon chain. But their fries are still as good as they were before. And since “self-indulgence” was the theme of my afteroon, it all seemed fitting.

Speaking of indulgence, what I wanted to purchase is a game: Enjoy Sudoku. I’ve been playing with the free “Enjoy Sudoku Daily” version for a while. This free version has a number of restrictions that the 2.99$ version doesn’t have. If I had had access to a credit card at the time, I would have purchased the “premium version” right away. And I do use the free version daily, so I’ve been giving this a fair bit of thought in the meantime.

So imagine my deception when, after redeeming my iTunes gift card, I noticed that I wasn’t able to purchase Enjoy Sudoku. The gift certificate amount shows up in iTunes but, when I try to purchase the game, I get a message saying that I need to change my payment information. I tried different things, including redeeming the card again (which obviously didn’t work). I tried with other applications, even though I didn’t really have a second one which I really wanted to buy. I read the fine print on the card itself, on the card’s packaging, and on the Apple website. Couldn’t find any explanation. Through Web searches, I notice that gift card purchases apparently work on the App Store portion of the US iTunes site. Of course, that web forum might be wrong, but it’d be surprising if somebody else hadn’t posted a message denying the possibility to use iTunes gift cards on App Store given the context (a well-known Mac site, a somewhat elaborate discussion, this habit of forum posters and bloggers to pinpoint any kind of issue with Apple or other corporations…).

The legal fine print on the Apple Canada website does have one sentence which could be interpreted to legally cover the restriction of applications from purchases made with the iTunes gift card:

Not all products may be available.

This type of catch-all phrasing is fairly common in legalese and I do understand that it protects Apple from liability over products which cannot be purchased with an iTunes gift card, for whatever reason. But no mention is made of which products might be unavailable for purchase with an iTunes gift card. In fact, the exact same terms are in the fine print for the US version of the iTunes store. While it makes a lot of sense to embed such a statement in legal fine print, making people pay direct attention to this statement may have negative consequences for Apple as it can sound as if iTunes gift cards are unreliable or insufficient.

I eventually found an iTunes FAQ on the Canadian version of Apple support which explicitly mentions this restriction:

What can I buy with an iTunes Gift Card or iTunes Gift Certificate?

iTunes Gift Cards and iTunes Gift Certificates can be used to purchase music, videos and audio books from the iTunes Store. iTunes Gift Cards and iTunes Gift Certificates may not be used on the Canadian store to purchase applications and games. iTunes Gift Cards and iTunes Gift Certificates are not accepted for online Apple Store purchases.

 

(Emphasis mine.)

As clear as can be. Had I known this, I would never have purchased this iTunes gift card. And I do accept this restriction, though it seems quite arbitrary. But I personally find it rather strange that a statement about this restriction is buried in the FAQ instead of being included on the card itself.

The US version of the same FAQ doesn’t mention applications:

What can I buy with an iTunes Gift Card or iTunes Gift Certificate?

iTunes Gift Cards and iTunes Gift Certificates can be used to purchase music, videos, TV shows, and audio books from the iTunes Store. At this time, iTunes Gift Cards and iTunes Gift Certificates are not accepted for online Apple Store purchases.

Since, as far as I know, iTunes gift cards can in fact be used to purchase applications, the omission is interesting. One might assume that application purchases are allowed “unless stated otherwise.” In fact, another difference between the two statements is quite intriguing: “At this time” iTunes Gift Cards are not accepted for online Apple Store purchases. While it may not mean anything about Apple Store purchases through iTunes cards in the future. But it does imply that they have been thinking about the possibility. As a significant part of Apple’s success has to do with its use of convenient payment systems, this “at this time” quote is rather intriguing.

So I feel rather dejected. Nothing extreme or tragic. But I feel at the same time disappointed and misled. I’ve had diverse experiences with Apple, in the past, some of which were almost epic. But this one is more frustrating, for a variety of reasons.

Sure, “it’s only 25$.” But I can do quite a lot with 25$. Yesterday, I bought two devices for just a bit more than this and I had been considering these purchases for a while. Altogether, the webcam, mouse, and Sudoku Daily were my holiday gifts to myself. Given my financial situation, these are not insignificant, in terms of money. I’ve had very positive experiences which cost much less than 25$, including some cost-free ones but also some reasonably-priced ones.

But it’s really not about the money. It’s partly about the principle: I hate being misled. When I do get misled by advertising, my attitude toward consumerism gets more negative. In this case, I get to think of Apple as representative of the flaws of consumerism. I’ve been a Mac geek since 1987 and I still enjoy Apple products. But I’m no Apple fanboy and occasions like these leave a surprisingly sour taste in my mouth.

The problem is compounded by the fact that Apple’s iTunes is a “closed ecosystem.” I listen respectfully to others who complain about Apple but I typically don’t have much of a problem with this lack of openness. Such a simple issue as not being able to use an iTunes gift card to purchase something on the iTunes App Store is enough to make me think about diverse disadvantages of the iTunes structure.

If it hadn’t been for the restrictive App Store, I could have purchased Enjoy Sudoku directly through Paypal. In fact, the developers already have a Paypal button for donations and I can assume that they’d be fine with selling the native application directly on their site. In the US, I could have purchased the application directly on iTunes with a US Paypal account. In this context, it now seems exceedingly strange that iTunes gift cards would not be usable on the iTunes App Store.

Which brings me back to a sore point with Apple: the company is frequently accused of “hating Canada.” Of course, the sentiment may be associated to Canadian jealousy over our neighbours in the United States. But Apple has done a number of things which have tended to anger Canadians. Perhaps the most obvious example was the fiasco over the Canadian iPhone as Rogers and Fido, Canada’s only cellphone providers for the iPhone, initially created such abusive plans that there was a very public outcry from people who wanted to purchase those cellphones. Rogers later changed its iPhone plans but the harm had been done. Apple may be seen as a victim, in this case, but the fiasco still gave credence to the notion that Apple hates Canada.

Yet this notion isn’t new. I personally remember diverse occasions through which Canadian users of Apple products had specific complaints about how we were treated. Much of the issues had to do with discrepancies over prices or problems with local customer support. And many of these were fairly isolated cases. But isolated incidents appear like a pattern to people if they’re burnt twice by the same flame.

Not that this means I’ll boycott Apple or that I’m likely to take part in one of those class action lawsuits which seem to “fall” on Apple with a certain regularity. But my opinion of Apple is much lower this afternoon than it has been in the past.

I’m sending the following to Apple Canada’s customer service (follow-up: 62621014). Not that I really expect a favourable resolution but I like to go on record about things like these.

I would like to either be credited 25$ for purchases on the App Store section of the iTunes store or reimbursed for this gift card.

I bought a 25$ iTunes gift card specifically to purchase applications on the App Store. The front of the card’s packaging says that I can use it “for music and more.” Nothing on the small print at the back of the packaging or on the card itself says that the card may not be used on the App Store. Even the legal terms of the card have no mention of this restriction:

http://www.apple.com/legal/itunes/ca/gifts.html

The only passage of that page which can be understood to cover this exception is the following:

Not all products may be available.

Bringing attention to this sentence may not be a very good strategy as it can imply that some music, videos, and audiobooks are also restricted.

The only explicit and direct mention of this restriction is here, in the support section of the site:

http://www.apple.com/ca/support/itunes/store/giftcard/

What can I buy with an iTunes Gift Card or iTunes Gift Certificate?

iTunes Gift Cards and iTunes Gift Certificates can be used to purchase music, videos and audio books from the iTunes Store. iTunes Gift Cards and iTunes Gift Certificates may not be used on the Canadian store to purchase applications and games.
