    How do you do it with Cydia doing all the work for you? I don't see the option in Cydia, I must be blind. And how do you restore using Cydia if it is saving the blobs for you if you upgrade, how would you be able to access Cydia to access your backed up blobs, if that makes sense...

    Cydia does it automaticaly, when you open it at the very top of the main page itwill have a message saying if this device has its SHSH backed up.


    I personaly save my own copy of my Blobs with the firmware umbrella app.

    Thanks, I never noticed that little print. I was looking for a button or something. So if Cydia has it on file, let's say I accidentally upgraded the device to iOS in the future...if it is stored via Cydia, which you need to jailbreak to get, how would I access my blobs to restore to 3.2?

    Cydia auto backs up your blob to Saurik's Server.


    The process is very simple all you have to do is to add Saurik’s Server address to your system hosts file. This trick make iTunes thinks it is talking to Apple, it is talking to Cydia instead while the restoring process. Doing this will allow iTunes to access signatures already stored by Cydia “on file†feature. In simple words this duplicates the functionality exposed by Apple’s signature server, except using “on file†results rather than live request.

    Note:

    This process is only for those who saved their SHSH to Cydia Server already.
    Don’t use this procedure for 3.0.1, because Saurik Server do not have signatures for 3.0.1
    Read the process and Saurik post two-three times before starting the process.
    iPhone unlockers note that by doing this you can downgrade your firmware only, your baseband is still at 05.12.01 which is un-hacked at the moment.

    I'm already backed up on cydia so the note doesn't apply right?

    Downgrade iPhone 3GS OS 3.1.3 to 3.1.2 With Cydia SHSH | jailbreak



    The blob is used to downgrade if you for some reason upgrade to a new firmware that has no jailbreak. This however will not save you from BaseBand upgrades meaning even if you downgrade firmware and are able jailbreak agian you may not be able to UNLOCK any more.

    BaseBand only applies to iPhones and iPad 3G.
