Q: Can I update my 3.1.2 (7D11) Ipod touch to a newer version?

The Software Update function was introduced in iOS 5.

You will have to update with iTunes.

Which iPod model do you have:

If you are running 3.1.2, you either have a 1st gen, a 2nd gen, or a 3rd gen.

A 1G can run 3.1.3

A 2G 4.2.1

And a 3G 5.1.1

Update Server

Try:

- Powering off and then back on your router.

- iTunes for Windows: iTunes cannot contact the iPhone, iPad, or iPod software update server

- Change the DNS to either Google's or Open DNS servers

Public DNS — Google Developers

OpenDNS IP Addresses

- For one user uninstalling/reinstalling iTunes resolved the problem

- Try on another computer/network

- Wait if it is an Apple problem
