I've searched and could not find this specific issue. I have an iPhone 4 untethered and jailbroken. The phone is slow as **** and I need to restore. I've restored before through iCloud without any issues. However, now that 5.1 is out, I'm concerned that I may be forced onto 5.1 when iCloud restores. If I perform an iCloud restore, will I be forced onto iOS 5.1 or will I remain on 5.0.1?
