So I'm headed to AT&T Wireless to day to get a new GSM phone. I was really hoping to wait for the T600, but circumstances have forced me to upgrade now. Which is the bette rof the two phones below? Sony-Erricsson T616 Motorola T721 i'm looking for something small enough ot go in my pocket, color screen, polyphonic ringer, and WAP/Internet enabled. SMS and AIM are nice options, as are the camera, but are not deal breakers. Are there any other phones I should be considering?
