    you need your shsh blobs i believe. But you probably don't have them so you can't downgrade.

    You need SHSHs to downgrade to 4.0. You should downgrade to 3.1.x for a 3G anyway, it runs better. Just shift+restore to it. If you get error 1011 1013 or 1015 its good, you did it correctly. Just kick it out of recovery mode with Recboot and jailbreak after. You should be up and running then.

    A 3G is jailbreakable on 4.0.2 with redsn0w 0.9.5b-5 and apple is still signing 4.0.1 so you could downgrade to that and use jailbreakme

    Shift+restore to 3.1.2

    Kick outta recovery mode after restore error 1011 1013 or 1015 with either TinyUmbrella or Recboot.

    Jailbreak with Redsn0w 0.9.3.
