How do I get my iPod Touch from 2008 to start up? Or what are good Google keywords to figure it out?

You know how you need iTunes to be able to start up an old iPod? It tells you to plug it in to iTunes before it even starts up. The problem is, newer versions of iTunes do not sync with this device. So how can I go about bypassing this? Or at least, how do I correctly Google how to do this?

Download an older version of iTunes compatible with your iPod.
