hi guys, sorry if this is a SUPER-NOOB question, but I have googled for hours and haven't found a working answer... Basically I have a xt912 that I got from verizon... I love the phone and I'd like to keep it and move somewhere with a cheapr contract. I am interested in t-mobile in particular... I read online that if I put a sim card from a different company on the phone a menu would come up for an unlock code to be entered. fortunately I haven't purchased an unlock code yet, because a menu didn't come up at all. all my phone said was "incompatible sim inserted." I played around a bunch and could not find any way of inserting a different sim. Thoughts, anyone? basically I just want to unlock my xt912.... if I can't I will have to ebay it and buy another phone that is probably not as good... Thanks a lot!
