So I've tried multiple things and NOTHING will work. I've used quickpwn on 2.2.1 and with the original ATT sim card, quickpwn doesnt unlock it because the t-mobile card wont work in it, and I even tried running quickpwn with the TM card inside the phone like I had read somewhere... Anyone have any suggestions? I unlocked my old 2g phone on 2.0 and it was cake, for some reason it wont work on my friends phone. Thanks in advance!
