Need help unlocking iPhone 3GS 5.0.1 BB 6.15.00 oldbootrom . I also have T-mobile carrier.
I've spent over 6 hours trying to unlock my iPhone3GS, I got it as 5.0.1 BB 5.13.04. Updated to Ipad BB, and also downgraded and tried to unlock with ultrasn0w, restored it as fresh 5.0.1, and even used sn0wbreeze. All no good .
