Can you disable Internet on a 4th generation iPod?

Answer 1

You can restrict the internet from being used on the iPod Touch.

1. Go to settings.
2. Go to restrictions (if not there, go to general and then to restrictions)
3. Enter a four digit pin to access the restrictions (first time restrictions means you make up the pin)
4. Set the restrictions.
5. Write down the pin so you don't forget it.

Answer 2

Yes, in settings you can put your iPod on "airplane" mode, which will disable the Wi-Fi connection.
