My buddy has a T-mobile iPhone that he had activated for him. I made the mistake of trying to update his software through iTunes and completely wiped out his phone. On iTunes it now says "The SIM card inserted in this iPhone does not appear to be supported" and on his iPhone it goes back to the original activation where it wants me to plug in and install through iTunes. What do I need to do to get his phone back to normal again? Help would be greatly appreciated. Thank you in advance.
