iH8sn0w, the famous iOS developer behind famous tools like Sn0wbreeze, iFaith, iReb and f0recast has finally found a way to downgrade iOS 5.1 to iOS 5.0.1 for the A5 powered iPad 2 and iPhone 4S. Until now downdrating the iOS firmware was not possible for the iPad 2 and iPhone 4S as they are powered by the dual core A5 processor. Apple once after releasing any update for the iOS stops signing the older firmwares and hence official Restores result in the installation of the latest firmwares on their device. This is especially done to keep all devices up to date and to curb Jailbreak activities which Apple doesn’t approve of its devices.
Once the device is updated to the latest firmwares than users are unable to Jailbreak it until the Dev Team releases a Jailbreak Tool for the new iOS. Other iDevice users like those of iPhone 4, iPad 1, iPhone 3GS and iPod touch can easily perform the task of firmware downgrades of they have the SHSH blob saved for it.
Jailbreak fans also have popular tools TinyUmbrella can detect and save the SHSH blobs locally on their device. Cydia also quickly recognizes the available SHSH blobs and updates Cydia Apps with respect to the SHSH blob saved.
iPad 2 was released last March and the iPhone 4S since October but these A5 devices still do not have a way to save SHSH blobs. The Canadian developer iH8sn0w has finally found a loophole in the APTicket system which will allows users to save SHSH blobs for their device. The silver lining is that according to iH8sn0w the same loophole can be worked with the new iPad which is shipped with iOS 5.1 installed on it.
Now finally the iPad 2, iPhone 4S and the new iPad users can downgrade their iOS firmwares to get the Jailbreak benefits on their device. There is no ETA for the tool and also we do not anything more than just that it works on APTicket system. We can expect a week for the new iFaith tool. Keep visiting GeekPrison for more information.
