Anyone have any idea why my iPhone won't activate and iTunes says "The SIM card inserted in this iPhone does appear to be supported"? I had my iPhone 3G exchanged earlier today and the Apple Genius who dealt with it for me activate the phone with my SIM card in it. I've been using it al day no problem. However, it had 2.0.2 on it so I upgraded it to 2.1 and now it wont activate, it gives the above error message. Nothing is different about the SIM card, I tried it in another iPhone and it works fine. I've tried restoring the phone 2 or 3 times but no good. Anyone come across this before and fixed it?
