Hi guys, Spec: Iphone 3Gs 3.1.2 - 05.11.07 Recently I jailbreak using pwnage then blackra1n/blacksn0w to unlock my iphone 3gs (3.1.2 - 05.11.07). So I decide to get one for my girlfriend same spec (3.1.2 - 05.11.07) and when I did the same process, itune gives the 1600 error during custom firmware restore. I later discovered it had a newer bootrom on this one and Untethered jailbreak (pwnage) wasnt supported. The iphone is currently stuck in DFU mode and unable to enter recovery mode and gives the 1600 error upon restore, I tried using new cable and switched from Mac to PC for the restore but none worked. With iREB not supporting 3gs. I am out of ideas anyone can help to restore the iphone? I should have just used blackra1n (tethered) jailbreak and unlock it I guess I can normal restore it to 3.1.3 and have a itouch instead if worst come to worst. In addition I have a question about blackra1n (tethered) jailbreak/unlock, I was under the assumption if I powered off I will loss the unlock, but thats not the case on another iphone? Any comments.
