Whats the point of saving shsh blobs?
Can somebody explain what is the point of saving shsh blobs?
I don't even know what a blob is......
I've been on iPhone for 2 months. Bought a used ip4 that was on 4.1. Used limerain to JB that. Then when greenpoison came out for 4.2.1 I upgraded my firmware via tunes then used greenpoison.
What are shsh blobs? And why do we need to save them?

I found a bunch of them on iClarified... used them to downgrade my daughter's iP3 after she tried iOS 4.x.

here is a decent explanation:
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 load a 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.

Some people update before a jailbreak is available and decide they want to go back. Some find that newer iOS versions run slowly on older devices. I used my blobs to update from 4.0.1 to 4.1 when Apple would only allow updating to 4.2.1, which at that point was only available as a tethered jailbreak.
