I'm about to get a new iPod so I wanted to try downgrading back to iOS 1 for fun. is this possible? i was going to try to put in into DFU mode, run the firmware on it, and then just run recboot. could it work?

New devices only work on the current and further iOS softwares.
1G iPod can have - 1.1 and higher
2G iPod can have - 2.1.1 and higher
3G iPod can have - 3.1.1 and higher
4G iPod can have - 4.1 and higher
So if you buy a 1G iPod Touch you might try, even though it will be hard since Apple no longer "seeds" that built so you'll have to find a program like TinyUmbrella to help you with it.
