Jail breaking a 2G Iphone with 2.2 firmware.?

I am running windows Vista.. And from what I'm seeing they make in-depth guides how to do this depending on the computer.. Do you guys have any links or any guide showing how to do this with the 2.2 firmware? I really would like to do a quickpwn on it seeing that it is the most simplest form of jail breaking. Again it is a 2G Iphone with 2.2 (the latest firmware from itunes) and im running Windows vista on my computer. All help will be appreciated, thanks-
