The folks over at iFixit.com have disassembled the new second generation iPod touch and fourth-gen iPod nano. And it's only been a couple of days since Steve Jobs and company introduced Apple's latest goodness to the world! So if you've been wondering about the innards of your favorite music player (handheld computer and gaming platform in the iPod touch's case), here's your chance to find out.

iFixit walks you through the whole process, posting a series of pictures and a detailed explanation of what they did and found out about each iPod. For instance, did you know the iPod touch 3G has a Bluetooth chip? We didn't. Apple's said nothing about including Bluetooth in this handheld.

Why does iFixit perform these disassemblies? So you'll have a source to go to should you ever need to take apart your devices.
