I assume you are using either AT&T Wireless or Cingular. There will be no new GSM/TDMA handsets available. That was only a temporary bridge between the two networks. None of the older GAIT (GSM/TDMA) phones are compatible with the new MP3 ringtones.
I have AT&T wireless service in NH. I have the phone I do now because I need to utilize GSM, TDMA and analog networks. My current phone is the Sony Ericsson T62u. It's OK, but I'm jealous of all the phones out there that have MP3 ring tones. Does anyone know of a phone I can use that can receive those networks with this capibility? Thanks
