Man, I hope your right cause then there is hope.
And it's nearly impossible to do any permanent damage to your iPod in attempting to jailbreak it, the most damage you could do would having to restore your iPod.
I had a very difficult time attempting to Jailbreak my iPod Touch 2G 8gig MC model running 4.1
The first time I was able to downgrade the firmware to 4.0 and use Jailbreakme.com however, my iPod would not go into DFU mode at all, no matter what I tried so my downgrade wasn't a 'clean' downgrade and the iPod didn't run well at all plus there was some pixilation in the screen. I restored it back to factory settings and studied some more.
I was able to discover a modification to the ipsw file that would force the iPod into DFU mode after it was loaded. I thought great! I'll give that a try.
Well, I didn't do it quite right, there were various reasons for this but all told I modified the wrong file. My iPod will not turn on, Windows XP Pro informs me that my device is corrupt or damaged and it will not 'see' the iPod.
I really don't want to accept the fact that modifying a file would physically damage the hardware, but the iPod is a coaster right now.
What point am I trying to make? Well, you should know that yeah, it is possible to hurt your iPod, so be careful and read the directions a BUNCH of times. If the directions don't fit your situation to at least a 95% look for another option. If you can't find something that fits, wait. But, never, never give up!
It's your device, do with it what you will.
