Hi huntt,

Welcome to the Apple Support Communities!

I understand that you have an iPod touch (2nd generation) that you would like to update. Because of the older model of iPod touch, you will not be able to update over Wi-Fi, but you can update using iTunes on your computer. Please follow the steps in the attached article to complete this process.

Update the iOS software on your iPhone, iPad, and iPod touch - Apple Support

Update your device using iTunes

If you can’t update wirelessly, or if you want to update with iTunes, follow these steps:

1. Install the latest version of iTunes on your computer.
2. Plug in your device to your computer.
3. In iTunes, select your device.
4. In the Summary pane, click Check for Update.
   
5. Click Download and Update.

Have a great day,

Joe
