T Mobile screwed me over so now I hate them. I found an awesome Sony Ericsson phone but it is AT&T. I know I can unlock that phone but would I be able to use the Virgin Mobile prepaid service on it??? Virgin Mobile seems to be the best deal for me so I want that...ALSO, WHERE CAN I FIND THE SONY ERICSSON W580 CHEAP? AND DON'T JUST SAY E BAY.
