Miland Alvares at Smoking Apples:
For the full year that the first gen iPhone was out, the only way to put it to any real use was to jailbreak it. Then the app store came along and changed the game of using third party applications on iPhone OS. ‘Official’ apps were far more refined, polished, and as is evident by the current figures, far more in number. But if the App Store is famous for anything other than its sheer size, is the stringent rules by which Apple allows an application to be sold at the store. In most cases Apple doesn’t even have to reject the apps—the developers of the apps in question know they won’t make it. Yes, they are that cool.
