While Apple announced 7 tent-pole features for iPhone 4.0 including multitasking, folders, mail enhancements, iBooks, Enterprise features, Game Center social network, and iAd mobile advertising platform, it's important to remember we won't get the final feature set for iPhone 4.0 until Apple's World Wide Developer Conference (WWDC) this June.

Last year Apple showed off a lot of features for iPhone 3.0 in March, but it wasn't until WWDC that we saw features specific to the new iPhone 3GS hardware -- video recording, VoiceOver, compass, Voice Memo app, etc.

If iPhone G4 (not 4G!), also likely introduced at WWDC in June, has extra hardware like a front-facing camera, we won't see Mobile iChat video announced until then...
