    I just swapped the motherboard of two iPhone 3G 8GBs. One fully works and the other one doesn't. I swapped them so my green iPhone can have the unclocked mobo. The motherboard that went back in a black housing now says no service when I try my sim in it.

    I already tried to reset network settings. I been using the motherboard the whole day and it was working. I am using my At&t sim card and the phone is locked to at&t.

    EDIT: Finally got it to work. This mobo has been giving me these types of problems since I got it. I flashed it to 3.1.2 then up back to 3.1.3 and now it connects to AT&T. I had to do the same thing when I first got the phone.
