In case you’ve missed the news on Apple and their new subscription service, you should read the following: http://www.blog.montgomerie.net/thoughts-on-ios-content-purchase. What Apple is doing is pretty lame, considering until now everyone has had to deal with the fact that Apple hasn’t had subscription functionality in place. And now that they do, they’re saying “screw any solution you may have previously used” if you want to continue offering your services on the app store.
Not that it would in any way be enforceable, which is why they didn’t do this, but they should at least have some sort of grandfathered in system for apps like Netflix, Pandora, etc. that have up until now been on their own.
