How do I register this iPod to a computer?
I think I have to register my iPod o my computer before i can put music on it and listen, but I don't know how to do that.
iPods are very tricky due to DRM restrictions. For the simpliest of users you will need to download the latest iTunes and install it to your computer.
After iTunes is installed, simply plug in your iPod and wait. It should connect up and walk you through the rest.
