I have an iPhone 3GS which I upgraded to 5.1.1 custom sn0wbreeze IPSW from 4.2.1 two days ago and since then it has been giving me the Searching... signal then No Service. I know the reason, this was bought from the US and I live in Qatar but I've fixed this before by upgrading my baseband to 6.15.00 and unlocking it via Ultrasn0w.
I also have an AT&T SIM just in case. I've tried several things to try and fix this but to no avail. I've tried turning it off a few times, and played around too. I've tried the Ultrasn0w fixes in Cydia, NOTHING is working.
Any help would be appreciated, thanks.
