Synopsis: 8 GB Iphone bought in 11/08 with stock 2.1 firmware. Chose to downgrade to 1.1.4 but only EN_Ziphone baseband downgrade and and Ziphone 3.0 would work after I tried several other tools. Unlock and Jailbreak successful at 1.1.4 I did a restore to stock 2.2.1 firmware. Phone rebooted in factory locked state. Tried Quickpwn 2.2.5 and followed all instructions. Phone rebooted unlocked, however when I insert my tmobile sim, status changes between "no service" and weak 1 bar signal - unable to make or receive calls. I have tried restoring to stock and Quickpwn several times with no results. ideas?
