My iPhone will not get any service at all, no matter what sim?

[Hf44]

I had my iphone on 5.0, running my gevey sim on 4.10.01 PBB. For months i was using a gevey tehered unlock with tmobile perfectly fine. Recently it stoped working and i restored to see if it was a firmware problem. No cigar.

I downgraded to 4.3.3 with my saved SHSH blobs, and tried using my gevey, but nothing worked. I then tried using a ACTIVE AT&T simcard, and one bar was shown, but then NO SERVICE. I tried that active at&t simcard with another iphone 4, and it worked fine, so it must be my phone or firmware? I have spent over 18 hours over the last 3 days.. please help.

is there anyway i can wipe my phone that every speck of firmware can be deleted? or is my baseband corrupted? ugh

Only thing you can try to ensure that is to do a factory wipe. And then a DFU restore.

If that doesn't work, try going here for help:

is a factory wipe like a restore?

No, it's Settings > General > Reset > Erase all content and settings. It wipes your phone's filesystem, at wch point you must then restore.
