I just updated me previously jailbroken 1.1.1 to 1.1.4 and jailbreaked/activated the phone using Ziphone 2.5c. I'm on an AT&T network with the SIM card but now my iPhone won't even recognize that the SIM card is in there. I've tried resetting the settings and restoring a couple times, but none of it seems to work. I don't want to register through Apple/AT&T cause I don't want to have a 2 year extended contract. Do you guys know what is wrong and how I can fix it? I didn't unlock the phone either, but I don't know if this would somehow help my situation.
