    not at all, screwed if you want an unlock however.

    download 3.1.3 firmware then just shift/option click on restore in itunes and select the 3.1.3 firmware. then use spirit to rejailbreak if you'd like and you're good to go!

    I followed the instructions here and downgraded successfully. It mentions Recboot, which I used and it worked perfectly.
