He wants to "un-jailbreak". The only way to remove a jailbreak is a restore in iTunes which erases the entire contents of the phone. If you do a back-up first you can save your contacts, photos, text messages and music. After you're done restoring just use the back-up iTunes makes to put all your stuff back on.
