http://jailbreakme.com
let it install and it should put install.app on your ipod then in there. Go into installer hit refresh/reload then under "install" choose all programs and look for one called community sources. You might have to refresh the install list a few times for it to show. Once you see community sources install it then back to the list of all programs you'll see a folder on installer called tweaks 1.1.1 in there you want to install oktoprep.
