How To Check And Save SHSH Blobs
Currently if you are on iOS4 and havent saved any previous shsh blobs you are pretty much stuck. This simple program allows you to save shsh blobs for your iPhone if you are using 3.1.2 and 3.1.3 which is a must for anyone who wants to jailbreak or unlock in the future. You cant even downgrade from iOS4 unless you have previously saved your shsh
My main bonus for this program is when you use it on an iPhone you can check if any SHSH blobs have been previously saved on the Cydia database.
