I've had all of the beta versions of iOS 4.2 and now the GM, and it's looking like AirPlay was removed from the iPhone 3G. iOS 4.2 Beta 2 had AirPlay available on my 3G, but now with the GM, it's missing. And before you ask, yes, I'm on a network with an AirPort Express that has AirTunes enabled. I can play to that AirPort Express through iTunes on my Mac Pro, so I know that it's not the network or the AirPort. Has anyone with 4.2 GM on an iPhone 3G been able to get AirPlay to work?
