I have recently unlocked my Iphone for 3.0.1 using redsn0w 0.8 and everything appears to have gone smoothly. I followed all the instructions and restored to 3.0.1 and then used the 3.0 firmware file to unlock and jailbreak. Unfortunately after the process is completed i seem to be unable to receive any calls or texts with my T-mobile sim. My phone shows full signal bars, its weird, i can make calls and send out texts the problem just seems to be with receiving them. Any help with this problem would be greatly appreciated.
