the ipod hacks forum has a sticky with links to downloads. otherwize just google. I'm sure there are a good number of sites with it.
also, the reson you can't jailbreak it is because apple put a diferent chip in the new touches. if it came with 2.x and has phisical volume buttons, then it's the new one. whether you can still jailbreak 1.1.4 on it or not, I can't say.
