    I'm on 4.0 and want to go back to 3.1.3 thought my blobs were saved, looks like they're not.

    If apple doesn't let us downgrade with such a **** OS that is complete BS.

    Am I stuck on 4+ and screwed here or is there any way down?

    Thanks and I searched but I didn't find exactly what I was looking for. I'm sorry because I'm guessing it does exist =(

    Yes, you can downgrade your 3G to 3.1.3, tools you need is :
    Tiny Umbrella, Redsn0w 0.9.4, 3.1.2 ipsw and 3.1.3 ipsw.
    Put your iphone into DFU mode
    Do the Shift + Restore to 3.1.3
    Error 1015 pops up : Use Tiny Umbrella to kick it out
    Now you are at Emergency Screen.
    Run Redsn0w and point to 3.1.2
    You are all set.
