I will be selling my iPhone 4S on Ebay soon so I can upgrade to the iPhone 5, but I want to sell the device jailbroken and software-unlocked. So, all I need to do is do a device restore on my 4S and re-jailbreak it, right? I'm asking, because I heard a while back that Apple disabled the ability to manually apply an iOS firmware during an iTunes update or restore, and updates it during this process. I want to keep my hackable firmware, but still delete all my personal information. Are there any extra steps that I need to take?
