I got a world phone. it's cdma and tdma (gsm). it's a mutli-band phone that can do cdma (verzion/sprint) as well as inserting a sim card and using att or tmobile. when I got the phone, it had a verizon gsm sim card in it for world roaming travel, but I got it sim unlocked and can switch from verizon to tmobile (I'm using a tmobile prepaid sim card). I think only HTC makes those world phones at the moment.
