Hi I have an unlocked iphone to 1.1.1 that was working fine in Malta with a local si card. The phone is 1.1.1 original, downgraded to 1.0.2 unlocked then back up to 1.1.1. However today it was working fine then it just switched off and does not want to start back up. Tried connecting it to power or PC but no avail.

What do you think happened?

Should I restore....to 1.1.1 or 1..0.2 if yes?

WIll I birck it?

Will I lose the unlock. I have synced it with Itunes

Your help is much appreciated!!!! Thanks in advnace
