    Yes, if you have your 4.0 SHSH backed up. Unless the device came with 4.0.2, then you can't downgrade no matter what.

    1) Add 74.208.10.249 gs.apple.com to you host file.
    2) Put device in DFU mode (hold power+home for 10 seconds then release power button and keep holding home button until itunes recognizes ur devide)
    3) Shift - Restore
