Apple has just gotten off stage at the World Wide Developers Conference, announcing the iPhone 4. But more importantly they're highlighted the iPhone OS 4, and renamed it iOS 4. Why rename it?
Well first the iOS is also on the iPad. But I don't believe that is enough of a reason for the change. The more interesting implication is that the iOS will become a wider device OS that Apple will keep developing hardware for.
Apple TV? Maybe. But be sure that Apple will release information late and that hype will build up.
