    Well for whatever version you want to downgrade to, you need to download that firmware version and then use pwnage to make a custom firmware. Follow the instructions in Pwnage to put the phone in DFU mode and then it will downgrade.

    I went from 3.1.2 to 2.2.1 using Pwnage 2.5 which is made for 2.2.1.
