My phone recently started giving me the no-wifi grayed out box, no service, and the "iphone cannont receive or make calls, restore with itunes" error message. I downloaded a 3.1.2 firmware and tried restoring twice with itunes, each time getting the 1013 error code.
I ignored it and jailbroke it with blackra1n and got it to turn on but still get the same error. When I go into my 'about' screen, I'm missing info. Heres what my screen looks like:
Well, i think u need a good FW load to fix it. Is it a 3G or 3gS? NP loading 3.1.2 with a 3G. Shift restore. Try another computet or a different version of iTunes.
