Finally the much awaited iOS 4.2 will be releasing within a few days and it seems as if the Jailbreaks and Unlocks will go public soon. The GM version of iOS 4.2 is already available for download and is targeted for Apple’s developer community for now. It is recommended to backup iOS 4.1 SHSH Blobs on their iPhone 4, iPhone 3G/ 3GS (Jailbroken or stock) before upgrading their handsets and devices to the iOS 4.2.
Why To Save SHSH Blobs?
