ipod not showing ios5 update or any other update.

Hi 🙂

Have you tried connecting your iPod to your computer or laptop? If you haven't then do so and download iTunes from here: http://www.apple.com/itunes/download/ then open it up and try to update your iPod from there.

Hope this helped 🙂 if you have any other questions i will be happy to help 🙂

You should also confirm your model of iPod here:

Only the third-gen iPod touch and later models can be updated beyond iOS 4.2.1.

Regards.
