I think I need to restore my jailbroken and unlocked 8Gb iphone. My ringer and alert sounds seem to have stopped. I'm worried about undoing what I've done so far. I unlocked with Pwng 2.1 and I'm not sure what I need to do. Will I lose everything Cydia installed, do I need to re-install. Could someone please offer some guidance. Also should I upgrade to Pwng 2.2 first?
thank you
