I recently updated my iPhone 3G to version 2.2.1, and it worked fine for all of a day.
The major problem is that I cannot make or receive calls. My phone will ring if a call comes in, but I can't answer. If I try to make a call, even with full signal and 3G, it might ring once before the signal completely drops and gives me a "Call Failed" message with the option to "Call Back" or "Cancel."
I tried restoring my iPhone to factory defaults, and it still gives me the same problem.
Any idea what would cause this? I'm desperate for any feedback.
