Got my New 3g Iphone delivered today. Took it out of the box got my sim from my old one and inserted it into the new one and connected it to Itunes. I got a message on the iphone screen ... No SIM card installed Insert an unlocked and valid SIM to activate Iphone. and on Itunes I get .... The iPhone "iPhone" cannot be used with iTunes because the information required for activation could not be obtained from the iPhone. Check that the SIM card is inserted in your iPhone and that it is not PIN-Locked. I tried resetting the iphone by holding down the power and home buttons but still no joy. After ringing O2 (UK) they advised me that there might be an issue with my origional sim card and I should go to an O2 store and pick up a post paid sim. I did this and still got the same messages. Now after speaking to O2 they said they think its fault and I should wait until tommorow before ringing up and arranging a doorstep swap. Am I alone or has anyone else experienced this??? Thanks a 'wanting to play' iphone owner.
