Alright, I need a replacement phone. I want to buy a sidekick, but I have AT&T
Both carriers ( Sidekick is Tmobile ) have GSM service, which means they have SIM cards. So if I take my sim card and put it in the sidekick, would it work? I know I wont get internet, and I've seen videos on Youtube of some kid just putting his sim card in.
Or if I have to unlock it, whats the easiest way? and how much will that cost :P
