I have a slight problem.. I have an AT&T iPhone 4S that has data on it, and I would like to obviously remove this data before selling. I know if I erase content via the phone, it will brick because it's already jailbroken. I know it I restore via iTunes, it will update to 5.1 and I couldn't re-jailbreak. Any ideas on how to make this work? What I need is the phone clean ready to go on 5.0 with Cydia installed... Crossing fingers! P.S.- Willing to paypal anyone $5 that helps me with a solution. I realize it isn't much at all, it's meant to be a gesture to show your time is appreciated.
