How do I jailbreak an iPod touch 2g running 2.2 firmware on windows?

i believe the 2nd gen did not come out with a jailbreak because the dev team did not make one for it yet i don't know why but you see all those pictures probably on google or where ever you find them it looks jailbroken cause they did that the the first gen and sent a screen shot to second generation ipod and viewed it as a picture so it looks like jailbroken
