My worry was about AT&T and the antennas. I remembered from last go-round that unlocked was T-mobile and didn't get the fastest AT&T antenna and looks like that might still be the case as well as no CDMA antenna. So while I am hanging on to my grandfathered plans I want the phone with the fastest antenna for that service but if it isn't subsidized, then I want it to work equally well on all services so I can choose what I want. I don't understand why Apple puts up with this from AT&T now that they aren't allowed to sell the subsidized AT&T iPhone.
