So I'm going a little mad now. I updated to ios5 preserving baseband to 4.10.01
I jailbroke with little problems.
I followed this tutorial..http://www.ijailbreak.com/iphone/unlock-iphone-4-with-gevey-sim-card-ios5/
I get to the point of turning airport on and off and it just doesn't find my carrier. The carrier option shows up but it just keeps searching and finally shows no service.
I've tried at least a dozen times. Tried with 3g on and off, reset network settings, turned off location settings. Nothing seems to work.
Anything I am missing here? My gevey worked like a charm with 4.3.3, but now I'm stuck.
Thanks in advance to anyone who can help me. I'd be willing to donate some cash if I get this fixed.
I HAVE THE SAME PROBLEM! did you ever fix it?
