I recently joined this forum and I have a question about SHSH blobs that I keep hearing about. I know what it does is lets you restore back to that firmware if anything happened but what is unclear for me is: How do you save it? Where does it save? So at any point in time if you want to restore back your phone even if its on a new firmware and your not jailbroken you can go back to your firmware that you saved your shsh in? its like a restore point? What devices you can do? I have a 3gs on 3.1.3 JB/UL can I save my SHSH?
