Sadly, I am in the same situation as you. I am waiting to jailbreak my 2nd gen 3.1, but there is no jailbreak yet. The Dev team is still working on it, but I believe that Greenpois0n will be released before them.

would desire to understand which verison of iOS you're working along with your ipod wish you have a abode windows pc, right here is what i did: I achieved a efficient tethered jailbreak on my ipod touch 2G one month in the past utilizing the RedSn0w gadget for abode windows 32 bit, and that i've got used Cydia and Installer completely. I rebooted or became off the ipod some circumstances provided that (just to confirm it became into achieveable)

Go get redsnow 0.8 run it do what it tells you to do it will say ISpw or something like that it's the folder where u save your iPod updates in put in your current firmware of your iPod then follow the directions
