I don't know why but this has been on my mind a lot. I can't complain about AT&T's data speeds. I'm pulling nearly 8Mbps down but when every new Android has radios with theoretical speeds of 21mbps, so it made me wonder why Apple didn't do this for the 4S? The one thing to come to mind is that they didn't want the phone to be flying fast on GSM networks and on CDMA be super slow? I'm hoping the next iPhone sports either a 21Mbps HSPA+ radio or 42mbp radio like T-Mobile's HTC Amaze/GSII.
