Just got my fil's old iPod.....trying to get apps for my son, but when I try to install it says "this app requires iOS 4.3". Do I have to plug it in to my PC? We're visiting them so maybe I'll have to wait?
iPod touch
To update
The Settings>General>Software Update comes with iOS 5 and later.
Connect the iPod to your computer and update via iTunes as far as your iPod model allows

A 1G iPod can go to iOS 2.2 via iTunes and iOS 3.1.3 via
Purchasing iOS 3.1 Software Update for iPod touch (1st generation)

A 2G to 4.2.1. Requires iTunes version 10.X. If a Mac it requires OSX 10.5.8 or later. With OSX 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 6.1.3 Requires iTunes version 10.7 or later. For a Mac, that requires a Mac with OSX 10.6.8 or later
A 5G to iS 7. Requires iTunes 11.1 or later if you update via iTunes
I suspect you have a 1g iPod those can only go to 3.1.3. The 1G does not have volume buttons on the left upper edge and has no speaker
