I have the No Service error, and I think its because my baseband and my 2.1 FW dont match. Even though ive done everything I can think of, (flashed 30 diff times with diff FW's apple and custom, used boot neuter to lock and unlock, iliberty, erased/downgrade baseband in ziphone everything) I still have no service.

So I want to restore back to 1.1.4, or even earlier, but how can I totally make sure my baseband is matching 1.1.4 and normal? Im pulling my hair out and am going to throw this thing at the wall soon.
