ok I updated my cousin's iphone to 3.1 with pwnage tool. I set the boot at 695 and checked activate phone. I left my sim card in and I get no display for my AT&T sim. Later I addd ultrasn0w and rebooted and put the apns and checked off t-mobile for the carrier. with the t-mobile sim in there was no display of T-mobile and it could make calls and on Edge it was so so so slow. I need someone to give me a step by step on doing this.
