What's the coolest things you can do with your iPod? I'm currently still using the old 30GB iPod video with a dual-boot between the iPod firmware and the Rockbox firmware.
A cool thing I like to use is the diagnostics menu. To do it, follow these steps:
> Hold down center and menu until the iPod resets
> Hold down center and left until the iPod makes a beeping noise and goes onto a black and white menu.
Now play around with it
