Finally Got 2.1 Installed

I was finally able to get the 2.1 firmware and SDK installed. After iTunes wouldn't update my iPod, I was able to boot the iPod while holding the Home button to force it into restore mode. After that, iTunes gladly downloaded the update and installed the firmware.

The new Genius feature is totally worth it, I'll say. Pick a song you want to hear and instantly create a playlist of 25 or 50 others from your library just like it.
