On Wednesday, September 17th Apple is expected to release iOS 8. This means that there only several hours left for those who need to restore their jailbroken iPhones to iOS 7.1.2 without losing jailbreak. After iOS 8 is released, the guys from Cupertino will no longer be signing iOS 7.1.2. In this case, if a user tries to restore the device using iTunes, he will be forced to update to iOS 8.
