We have pretty good news for the folks who have the newer generation devices on their hands, and love to jailbreak their devices on the newer firmware versions to modify the devices at the maximum level. As we know, Apple has recently released the iOS 5.1 for the iOS devices, and reportedly, the folks quickly updated their devices to iOS 5.1 through the OTA updates, and now looking for some guides to bring the jailbreak status back on their new-generation devices on iOS 5.1. The iOS jailbreak hackers recently released the iOS 5.0.1 untethered jailbreak for the iPhone 4S and iPad 2 devices, but now after the iOS 5.1, all the new devices again under the axe of Apple.
However, the major down-side of iOS 5 firmware update is that there is no way to downgrade the iOS 5.x to older 5.x.x firmware versions to regain the jailbreak status back on the devices, while after the launch of iPad 3, we have seen all the jailbreak hackers are now actively working on the iPad 3 untethered jailbreak, along with the A5 dual-core processor running devices iPad 2 & iPhone 4S on iOS 5.1, and the user who stuck on the iOS 5.1 is advised not to attempt any kind of trick with their devices, as if they applied any older trick on the device, the device will be bricked, and user has to contact Apple for repair.
However, on the other side, it is now reported that the famous iOS hacker behind the popular Windows jailbreaking tool, Sn0wbreeze, has just discovered a new exploit in the iOS 5 firmware version that allows him to downgrade his iOS 5.1 running device into the iOS 5.0.1, means the hackers have finally discovered an alternative method to Blobsmonster that now allows them to downgrade their devices.
iH8sn0w widely confirms that he is able to downgrade his A5 device running on iOS 5.1 to iOS 5.0.1 using the newly discovered apticket “loophole,” and the same trick would also be work on the latest iPad 3 devices. It means if you have the new-generation devices, now you will be able to downgrade the devices to older firmware versions with saved SHSH blobs.
Found a loophole in Apple’s apticket system. Restored my iPad 2 to 5.0.1 from 5.1. Works on all A5 devices.

Discovering a loophole in iOS firmware that allows you to downgrade iOS firmware version is actually a pretty big deal than discovering a jailbreak exploit, as if the trick works then million of users can easily downgrade their devices to older firmware version without any kind of Apple’s restriction on restoring devices. That’s a really good news for those who have iPhone 4S / iPad 2 devices, and recently they have mistakenly updated their devices to the latest iOS 5.1 firmware version and now wants to downgrade the devices to older iOS 5.0.1 to again jailbreak the device.
