The popular iOS developer and researcher, iH8sn0w, who is responsible
for the creation of Sn0wbreeze, iReb, iFaith and also f0recast has been
working hard again attempting to resolve a problem that has been
tainting the experience of the iPad 2 and iPhone 4S owners. The hacker
has found the exploit that will allow A5 device users to downgrade iOS 6.1.3 to iOS 5.0.1.
The iPad 2 and iPhone 4S are run by the A5 processor, and as any jailbreak fan knows, it hasn’t earlier been possible to perform firmware downgrades on these two devices. When Apple launches a new version of iOS, they quickly stop signing the older firmware, which means that any official restores result in the user setting up the newest official iOS version onto their gadget.
In typical situations, going to the newest iOS 6.1.3 is not actually a big problem for standard users. Nevertheless, the issue takes place when iDevice owners who want to perform a jailbreak update their software, leaving them having to wait with patience till the Dev-Teams create a working, distributable jailbreak for that fresh iOS version.

| Downgrade iOS 6.1.3 to iOS 5.0.1 on iPad 2 and iPhone 4S |
On older gadgets, users can usually benefit from a firmware downgrade to
versions of iOS that Apple no more signs once they have the relevant
SHSH blobs saved for that firmware.
Cydia automatically grabs any available blobs and update the users’ Cydia app using the blobs that have been saved. Jailbreak fans additionally use the popular and highly effective TinyUmbrella tool in order to quickly and efficiently get available SHSH blobs and save them locally on their devices for use later on.
Even though we've had the iPad 2 since March 2011, and the iPhone 4S since October, there has not been a method available to let users downgrade iOS 6.1.3 to iOS 5.0.1 on these A5 powered devices meaning that a restore is necessary for any reason that the newest firmware version would be installed.
Canadian iOS developer and hacker iH8sn0w states to have found a loophole in Apple’s APTicket system that helped him to successfully downgrade iOS 6.1.3 to 5.0.1 on his iPad 2.
The good thing is that he also believes that the loophole he has found will even allow firmware downgrades on Apple’s new iPad 3 running on the A5X processor. Of course this will only be possible when new firmwares become available mainly because that all new iPads were shipped with iOS 5.1, which is the current version.
The news simply means that the iPad 2, the new iPad and the iPhone 4S owners have finally been invited to the downgrade party and now they can downgrade iOS 6.1.3 to iOS 5.0.1.
