    I have a 3GS running on 4.0, it is a MB model and the serial goes 5K0142....
    I was wondering if there's a JB for it, or is there a way I could downgrade it back to 3.1.3
    I have shsh saved on saurik when I had it JB on 3.1.3

    So, in order to get 4.0 jb, you must downgrade to 3.1.3.

    There's no JB for 4.0 (3GS) yet.
