Note: I am aware that Zack posted a previous guide, but I've found that it is outdated, as BlackRa1n is no longer being updated by Geohot.
THIS ONLY WORKS FOR IOS 4.2 OR BELOW!
Download LimeRa1n here for the Windows version, or here for the Mac OS X version.

Step 1: Download the latest version of limera1n from the link above and save the application on your desktop.

Step 2: Double click on the limera1n exe to launch the application.

Step 3: Please ensure that your iPod Touch is connected to the computer.

Step 4: Click on the "make it rain” button.

Step 5: You will see that limera1n puts your iPod Touch in recovery mode. Immediately after this, follow the instructions.

Step 6: Limera1n will be prompt you to press both the home and power buttons.

Step 8: You will see that limera1n has put your iPod Touch in DFU mode. Continue to press the home button.

Step 9: While limera1n performs the exploit, you will see the limera1n logo on your iPod Touch.

Step 10: When limera1n has successfully jailbroken your iPod Touch, you will see “done” and get the following message.

Step 11: You need to restart your iPod Touch. You will notice that there is a new app called limera1n installed on your iPod Touch.

Does this work for 4.2.1?

I've never jailbroken an iPhone/iPod, but I've been reccomended to use Pwnagetool to jailbreak it. Dunno why though. :P

Pwnagetool is for tethered jailbreaks.

Greenpois0n is untethered meaning you jailbreak it and you are good.. nothing else needs to be downloaded and stuff, whereas a tethered jailbreak requires pwnagetool or some other tool to be downloaded to make your device function properly.

I recommend Greenpois0n because it is for 4.2.1 too and is easier I'd say. (Untethered+user friendly)
