Hello, By advance, sorry for my poor English level, It's not my native language. So here is the deal : I have an iPhone 4, and I recently upgrade to iOS 7 but I don't like it because Its not running smoothly ... I have jailbroken it in the past but not when I was on iOS 6 (I install iOS 6 "officialy"); It was way before that so actually I just have the SHSH blob for older versions of iOS (4.1 to 5.0.1 ...) Several questions : Can I downgrade it to 5.0.1 ? If yes, how I do that ? Will I be able to then upgrade to iOS 6 version [the latest one] even if I do not have blobs for it ? Regards.
