Apple gave a possible clue to an iOS 5 feature with a mention of automatic app syncing in iTunes. A check of the app updates page by Marcelo Alves showed that a device can be enabled for Automatic Download to get both purchased apps and updates directly, without having to link up to iTunes. No feature of the kind exists in iOS 4.3, leading MacRumors to suggest the notice (since pulled) was a clue as to what was in store at WWDC.
