If it's an original iPod touch, you can't. Otherwise, update it to iOS 4.2.1, 5.1.1, or 6.0.1 from iTunes on a computer.

Connect the iPod to your computer and update via iTunes if your model allows going to iOS 4
A 1G iPod can go to iOS 2.2 via iTunes and iOS 3.1.3 via
A 2G to 4.2.1. Requires iTunes version 10.X. That requires a Mac with OSX 10.5.8 or later. With 1OSX 10.4.11 you can only go to iTunes 9.X which gets you as high as iOS 4.1
A 3G to 5.1.1 Requires iTunes version 10.5 or later
A 4G to 6 Requires iTunes version 10.7 or later. That requires a Mac with OSX 10.6.8 or later

I haven't personally confirmed this(I don't have an iOS device), but some people have reported being offered to update devices to iOS 6 from iTunes 10.6.3 running on 10.5.8, and it is definitely possible to sync them unless they list 10.6.8 as an original requirement.
