So I updated to 1.1.3 and have no received a ton of problems. First, I was getting a weak signal when before, I had a strong one. Now the iPhone is telling me that there is no SIM card installed. Which blows my mind because the user doesn't install a SIM card, but whatever. How would you go about fixing this? Do I have to send it to Apple? I had tried restore and resetting everything. Nothing helps.
