| I was working for Qwest during the transition to Sprint, actually. The reason most of the phones switched over with just a PRL update was because the old network was also CDMA, the same as Sprint. Switching to AT&T's GSM network would require new phones since they're different network configurations (GSM also uses phones with SIM cards). And to the earlier post, yes, you can use phones from other providers on a different network (as long as they're both CDMA). You just need to be able to unlock the phone. |
