Steve only mentioned about 8 of the key ones. I am expecting these, some should have been there since day 1, but who knows, I am just a dreamer: - screen orientation lock. - faster iTunes sync - wireless sync - being able to drag and drop, copy, delete, transfer from the iPhone to your computer and viceversa - on screen bluetooth/wi-fi/airport mode toggling In iPhone OS 3 there are some hidden features that are never advertised. This weekend I noticed that I can still be on a phone call and sync my iPhone in iTunes, isn't that something? What are the other ones? As I remember there was a thread of iPhone OS hidden features, is there one out there for iOS 4?
