*Disclaimer* Jailbreaking voids your warranty. So be careful with your iPod because Apple will do nothing about it. Jailbreak at your own risk please.
First off make sure your iPod is updated to 3.1.2.
After that is done go to blackra1n.com and download blackra1n.
Plug in your iPod into your computer and once your computer registers it go and open blackra1n.
You should see a big button that says “let it ra1n”. Click on it and let it finish everything.
After it’s done you can close the program, BUT do NOT delete the program because you need it of you want to reboot your iPod. Open up the blackra1n app and install Cydia and/or Rock.
MAKE SURE YOU DO NOT DELETE THE BLACKRA1N APP. It will make errors.
Open up cydia or rock and install themes that you want. I recommend looking for Winterboard and Installous. Winterboard let’s you edit some stuff on you iPod. Installous let’s you install cracked apps off the Internet.
I hope this helps. Any questions either email me (info on about me page) or comment.
