Hey guys, I had had iPhone firmware version 1.1.3 and downgraded to 1.1.1 I followed all the steps (*#307#, 0, accept, hold, etc.) and jailbroke the phone. AppSnapp is on my phone, however I have No Service, at first it had no bars, now it says "No Service" I am an AT&T costumer, with an AT&T SIM card which worked before the downgrade/jailbreak. Does anyone know how to regain service without upgrading back to 1.1.3? Any suggestions would be greatly appreciated!
