How can i downgrade my ipod touch firmware from 4.0 to 3.1.2 when i have the MC model?

chose which firmware you want and download.
After downloading the desired firmware, you can shift-click (PC), or
option-click (MAC), the Restore or Update buttons in iTunes. A file
dialog will open and let you choose the downloaded ipsw-file.
Note: Your browser may change the ipsw-file into a zip file. In that
case just rename it to end in .ipsw and iTunes will accept it.
