So guys I got a new phone and am selling my old iPhone 4 on eBay. I'm selling it jailbroken on 5.01 and so I didn't want to restore it and lose the jailbreak and be stuck on 5.1. Since I'm somewhat paranoid, I want to make sure I delete everything I can so I feel secure selling it to a stranger. I can across a how to article on how to basically reset everything on the phone through the settings on the phone http://www.ehow.com/how_4704217_erase-personal-data-off-iphone.html Would this restore the phone like through iTunes, or would this be the way to delete everything and keep it on 5.01 and jailbroken? If not, what do you guys recccomend? Thanks!
