So far i am loving it.... I have a few questions. 1. Is there anyway to backup your phone while jailbroken? 2. What happens if apple releases an update for the phone and i want it. If i install the new update over this one will it corrupt the phone? will it unjailbrake it? or is it impossible to do it with a jailbreak. 3. if 2 is answered the way i think it may be it might answer 3 but. Is factory rest the only way to unjailbreak your phone? 4. WHAT IS SOME MUST HAVE APPS!!!!!!
