Hello everyone, I am new to this community, so please excuse any involuntary blunders... I have just moved from Mexico to the US. In Mexico I had been using an unlocked iPhone bought in the US. Tonight I connected my iPhone to my computer (still with the Mexican SIM) and iTunes said there was a new software I could download and install. When I did, iTunes said 'The SIM card inserted in this iPhone does not appear to be supported. Only compatible SIM cards from a supported Carrier may be used to activate iPhone. Please insert the SIM card that came with your iPhone or visit a supported Carrier's store to receive a replacement SIM card'. The worst part is, the iPhone went nuts and now will only let me make emergency calls! I need my contacts, pictures, music! Heeeelp! Thank you!
