iPod touch
To update
Connect the iPod to your computer and update via iTunes
iTunes 10 for Windows: Update and restore software on iPod, iPhone, or iPad
A 1G iPod can go to iOS 3.1.3
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
