So a mate of mine wants to jail break his phone but hes using firmware version 3.1. I know you can jailbreak this version but I can't seem to find an easy tutorial and most are for mac only. So I was wondering if there is a way to downgrade firmware to 2.2.1 so I can jail break it easy.

I tried using iTunes but I get an error (20) during the process and it f*cks up the phone and I have to do a restore which puts it back to 3.1 (even though it says factory defaults)
