Need some Christmas help - not syncing.
I bought an iPhone 3GS on eBay 2 months ago, it was 3.01 jailbroken + unlocked, and worked a charm. It recently kept turning itself on and off so I though, why not upgrade to 3.1.2 and re-jailbreak/unlock. Updated the firmware via iTunes, downloaded blackrain and made it rain. Jailbroke and unlocked it, the phone works fine (i.e. can use my sim and cydia etc.).
But when I plug it into iTunes:
"The SIM card inserted in this iPhone does not appear to be supported."
I can't restore or anything via iTunes, nor can I sync any new songs/videos/anything to my iPhone. There are no options at all just that message.
What can I do? Hopefully you people will help me, I've been looking around the internet for ages!
