Guys how do u factory a jailbroken iphone4? I wanna sell my iPhone but then when I click reset and erase all setting on the phone itself, it show me the loading circle for a long time. Then I press both home button with power button to get it back. So pls advise how can I do a reset. FYI I m on 5.1.1. I tried to hold the option on my Mac and select restore to my download firmware and click on 5.1.1 it doesn't allow me to install this. I think apple stop signing on this as ios6 is out.

How do u do a full restore? But by clicking on restore will it ask me to download iOS 6?
