Ok, go to Settings > General > About and tell me which carrier update do you have.

At&T 14.0

was the restore from a different phone? if not, this sounds like it may be an issue with the SIM card or the account provisioning. have you called at&t to ask them if theres not something wrong on their end?

I'm in the same boat and about to do a restore (undoing my JB), but afraid it won't help as per the comments I've been reading. Did you ever get this resolved? If so, what was the cause?
