Hi everyone, My hero has refused to accept any simcard. It was originally on Orange but from what I can gather from the previous owner was unlocked by one of those ebay blokes. The phone is being used on O2 and has worked for a few weeks since I had it but now al of a sudden the phone dispays an image of a simcard with an X in a red circle with the words emergency calls only at the bottom of the screen. I have tried two different O2 sims and a couple of Orange sims and all of them display the same screen. I have downloaded the latest Orange software from the HTC site and installed it and that has done nothing. Also factory resetted it before that. PLEASE HELP.
