IPhone3,3 is for CDMA with micro R-UIM card tray, similar with microSIM card for iPhone3,1; iPhone3,2 is for CDMA like in Verizon iPhone, you have to inject the phone number.
It's definitely iPhone 4G. I think that iPhone 4G will come out this summer (AT&T ONLY), follow by a January release on Verizon. This is why, iPhone going to Verizon will not impact AT&T as much. At least I think so. We won't see "iPhone 5" until Summer of 2012. THAT'S MY PREDICTION. I think if I'm right, iClarified should give me a prize or something lol.
