I know this isn't android, but I moved over the the big green robot and found a buyer for the iPhone 4. Was hoping this could stay here at least until I get an answer. I am on iOS 4.0 and the buyer wants it that way, As you know, Apple is no longer signing this firmware so I cannot just do a clean restore. I want to remove personal data (cleared the address book and mail manually). There are some remnants, such as the appstore that still has my personal data. It requires a password to get anywhere, but my email is still there. Not a huge deal, but ideally I would like to reset it so that the new buyer can manage it himself. Any help would be great!
