So I've been looking up some info on how to unlock an 8100 and it looks like it's supposed to be done in the Sim Card Menu... my question is does my sim card have to be in it. I don't want my sim unlocked, I'm looking to unlock my old 8100 and give it to my girlfriend so she can use my employee plan with AT&T. So do I need to put my sim card in my old phone and then call TMO for the unlock code or what?
