pls tell me the procedure for saving shsh and cn u share me ur gmail id we can chat live,if u can pls and +1 for u again.
SHSH Blob is a signature file which is verified against Apple Server to verify the the iPhone is running the latest version of iOS. If for some reason, when you are try to restore to a previous version, Apple will not allow you to restore it becuase, you are trying to load an older version of iOS. To make this possible, we need to send a request to a different server (Local or designated) which sends a SHSH blob (which was saved by you) back to iTunes faking that its the current version.
This will only be possible if you save the SHSH Blob for that particular version. ie iOS 5.0
