Hello, I have switched over from WinMo to Android and I LOVE it. I have a T-Mobile G1 which is unlocked and I am using on AT&T. I have it set up, am able to call, text, and web. I can even recieve MMS pictures but cannot send them myself. Everytime I try to send a MMS it fails. Why is this? Also, I am quite aware that I cannot get 3G with AT&T. Is 2G the same as EDGE? I am constantly on the EDGE network, but sometimes at my girlfriends or at school the E will change to G. What is the difference? Thanks in advance.
