QuickPWN is more designed for jailbreaking Firmware 2.xx than 2g, but it will jailbreak first gen ipod touch ie 2G. If you are speaking of 2nd Gen ipod touch, f
rom what im aware, there is no way to jailbreak the 2nd gen.
If you could next time please say 2nd gen OR first Gen (2g vs 3g), as some people try to refer to the touch as a 2g, which doesn't really make sense, it never had a fully mobile 2g connection.....
Having to restore an ipod is no big deal AT ALL. It just takes 5 min or more depending on how much stuff you have to reload. If you are worrying about redoing all your settings, seriously its nothing, because once you jailbreak your ipod touch you will want to reset everything and set it up around the great apps you can get.
