It was bit expected that Apple will soon stop signing the iOS 5.0 for iOS devices, as they have released iOS 5.0.1 earlier this week with a couple of security patches to iOS core system and tries to fix the iOS 5.0 battery draining issue on iPhone 4S. Apple releases the iOS 5.0.1 to fix the Miller’s highlighted a bug of iOS, which allow developers to easily run and execute any malware application on the iOS device through the App Store, without any knowledge of Apple and iOS device owner.

It is a quite bad news for those who are interested in iOS 5 untethered jailbreak, because iPhone Dev team and other iOS hackers announced earlier this month not to update your device to the latest firmware because it carries such patches to iOS core, which does not allow users to downgrade their devices to older versions even with saved SHSH blobs. The new iOS 5.0.1 update also comes up with jailbreak fixes, which may prevent now users from performing untethered jailbreak. In another report, hackers warned users that they have reached the final stage of iOS 5 untethered jailbreak, and if they update their firmware to the latest version then they will never enjoy the untethered jailbreak on iOS 5, especially on the iPhone 4S and iPad 2 because both devices carry next-generation A5 dual-core processor.

However, if you are not interested in iOS 5 untethered jailbreak, then no need to worry about this because it won’t bug you, and for those who were interested, sadly they will not be able to downgrade their devices to iOS 5.0 after the Apple’s signing. Because, as we have told before Apple has changed the route of SHSH in iOS 5, and to downgrade devices to older version will now require more resources.
