    As far as I know, you can downgrade any pre-3G device to pre-4.0 by simply shift-restoring. You'll need the right version of iTunes, and not sure if it's any different if it's an MC model.

    Really. I didnt think apple was signing any old firmware. Cool to know.

    To the OP: Go for it. Let us know how it goes.

    somewhere on this site, i read that pre-ipt3g doesn't need blobs, but my ipt 2g mb wouldn't accept the fw. so i had to use a custom fw thru sn0wbreeze but i did have 3.1.2 (the one i downgraded to) before, but i hadnt saved my blobs for some reason.

    1) Download the 2G 4.0 and the 2G 3.1.2 Firmware (ipsw) here:

    (had to remove link due to copyright sry) just use this its a link but not to pirated firmware:
    find firmware downloads here

    2) Download iReb from here:ih8snow.com

    3) Open up iReb, and choose offline iPodTouch 2G. (Your 3.1.2 file must be in the same folder.)

    4) Follow the instructions until its stuck on waiting for iBSS for ATLEAST 5 minutes, just to be safe.

    4 Okay listen, if your iBSS doesn't fail, wait until the sn0wflake appears on your ipod and wait for iREB to say done. Then, Skip to the part where you go into iTunes and restore 4.0

    5) Open itunes, Go to the ipod touch section on your left.

    6) Hold Shift, and press restore, then select your 4.0 firmware.

    7) Let it restore! Make sure you don't close anything!

    8) After your restore, you should be on 4.0 . You can check by Settings > General > About. 4.0 Boom Baby.

    9) Go to Jailbreakme.com ON your ipod touch, and press slide to jailbreak.

    NOTE: YOU MUST NOT SLEEP YOUR IPOD, CONSTANTLY CLICK ON IT. IF IT SLEEPS, INTERNET CONNECTION WILL BREAK, SCREWING UP YOUR IPOD.

    10) after all the loading screens, press home.

    11) Cydia will be in your homescreen.

    Hope I Helped

    I would remove that link. The place that allows you to downlad firmware.

    that's technically piracy. apple has a copyright on its firmware.

    remove that link
    or
    risk a potential ban
