...but having some competition is only good for AT&T iphone customers. if only apple would let t-mobile in on the iphone game, then we would have real competition between two GSM-based networks (which would mean you wouldn't have to buy a new phone to switch carriers, as you do if you want to go from an AT&T iphone to verizon. verizon has a CMDA, rather than a GSM, network. switching between the networks requires a difference in hardware, whereas switching between two GSM networks would just require a new SIM card)
