TinyUmbrella is the tool to save SHSH blobs of any iOS firmware for iPhone 4S, 4, 3GS, iPod Touch 3G, 4G, iPad 1, 2 and The New iPad and Apple TV 2G. BY saving SHSH blobs you can downgrade to old version of iOS firmware even after Apple has stopped signing that firmware and there by you can get back your jailbreak.
TinyUmbrella tool is developed by Notcom and regularly updated to support all new firmware versions. In order to use TinyUmbrella you must have java run time environment installed on your PC/Mac.
Not just saving SHSH blobs but Tiny Umbrella can also be used for entering into recovery mode or exit recovery mode and if you are stuck on boot loop then you can also fix recovery with Tiny Umbrella.
Under advance section of Tiny Umbrella you have couple of useful options such as request SHSH from Cydia, select directory to save SHSH blobs, change hosts file to point to Cydia server (useful when downgrading firmware).
Under General section you can view all the SHSH blobs saved for selected device along with other useful information such as serial number.
