I purchased a new iPhone 5 today and want to erase all the data on my iPhone 4s 16 GB before I sell it. It is Jailbroken and on iOS 5.1.1. I went into Settings, etc. and started the Reset. My phone has been showing the round rotating circle for the past 5 hours. I do not want to do a restore from iTunes because I want to leave the iOS at 5.1.1. I have a buyer and he does not want 6.0.
