    Hi I've justfound out about these shsh file checks apple do.
    I recently upgraded my 2.2.1 iPhone 3g to 4.1 through iTunes and it's don't that fine.
    Now I want to jailbreak and can't do 4.1 I want to downgrade it but I'm unsure if I downgrade to 4.0.1 (or around there) will my shsh checks pass?
    I will do the jb later I just want to get to the correct firmware to be able to jb first.
    Any advice would help I need to know all my options.
    Thank you

    You can just edit your post and I've heard some models don't need SHSH checks and if you hit the make my life easier button on Cydia, you should have them for all firmwares from 2.2.1 to 4.1

    You can safely downgrade, I hope the soft shsh doesn't take effect, just try, if it fails before restoring just hold home and sleep until it shows apple and boot it back up.

    If you don't have the blobs saved, and your 2G iPod isn't an MC model, then you can probably use pwnagetool to jailbreak at 4.0

    If he's on 4.1, without blobs saved, no matter what device he has. He cannot get to 4.0. Every device must save blobs now.

    You have to have been on a firmware to have SHSH Blobs for it. Greenpo1son is just around the corner though and soon you should be able to jailbreak soon.

    So should I not bother messing about with it and wait till 4.1 jb?
    It was jb before on 2.2.1 then directly updated to 4.1. Does this mean I can't downgrade no more too? Downgrade or wait???
    Anyone know what upcoming jb is going to be ready soon? For vista?
    It would make it easier for me to research it.
    Thanks for your comments guys

    You can't downgrade to a firmware that you have never been on. Just wait for 4.1 jailbreak. It'll be out soon.
