Many people are trying to Jailbreak their iPod Tocuh 2nd Gens now, and so of course there are going to be lots of "0MFG i BRIXED MEH IpOD111!one!!elven11@@@@@


" threads.
The fact is that it is not bricked. It would very *very* hard to brick an iPod or iPhone completely. You might be worried that iTunes isn't seeing your iPod, or it's not turning on. But all you need to do is a proper DFU mode restore. (Note: If the iPod has a white screen it's most probably in Pre-Jailbreak mode, which a few of the iPod Touch 2G jailbreaks require. If you're iPod has a white screen don't worry, it's a part of the process. So just continue with the Jailbreak)
The iPod is now in DFU mode, and should have a black screen, and shouldn't respond. iTunes will say it has detected an iPod in recovery mode, then simply click Restore and restore to original Apple firmware. Once it's done the iPod should be fully working again.
Now you can attempt to Jailbreak again, but make sure you meet all the requirements and follow the instructions carefully. And if you've tried any other Jailbreak (like a tethered one) I would recommend you do a DFU restore before doing the new un-tethered Jailbreak
Most of you probably knew this, but if not I'm glad to have helped in some way. If you have any problems I'll try my best to help, just try not to make another thread!
Happy hacking! 
Note: This will work with both iPods and iPhones.

- Turn the iPod off and make sure it's disconnected
[*]Connect it to your computer with iTunes open as you hold the Home and Sleep/Wake buttons (you might need an extra pair of hands for this. You've got less than 2 seconds to do this part)
[*]Keep holding them for another 10 seconds and DO NOT LET GO
[*]Release the Sleep/Wake button but keep hold of the Home button for a further 10 seconds (or until your computer recognizes it)
