    Shift+restore to 3.1.x.

    Get error 1011 1013 or 1015 is fine, just kick it out of recovery mode with Recboot. Then youre all set to jailbreak.

    You can also go to 4.0.1 as I think Apple is still signing it so you wont need SHSHs for it like you would with 4.0. Id recommend 3.1.x for 3G phones tho, runs better.
