Someone (if possible) should make an 'antijailbreak'. Its job: To remove all jailbreak data (Cydia, cydia packages etc.) from the device without harming the performance or corrupting any other data remaining on the device itself. Its aim: To allow users to 'remove' the jailbreak from the device without having to restore and lose all other data (music, contacts, pictures etc.) This would save a lot of time. If this is possible, please, someone give it a go. Thanks.
