I bought Jailbroken iPhone 5 on 6.1.2. How do I clear the phone to 'start fresh' without losing the jailbreak? (deleting all downloaded apps, cydia tweaks, etc.) I don't want to screw anything up or lose the jailbreak. Also, if the response is just "delete everything manually," could you please direct me to a list of default Cydia apps/tweaks so I don't delete something important. Thanks.
