I unlocked my iPhone 2g with PwnageTool 2.2 and now need to take my iPhone to apple for repair of a defective touch screen (dead strip). How can I virginize the baseband and firmware so that apple will not know the phone has been unlocked?
Just restore in iTunes and setup as a new phone. Then sync to keep all the call history, contacts, etc. Restore the new one to get all the info back, then re-JB.
