I just bought a ipod touch. I am unable to use it because itunes tells me I have no internet connection (unknown error 306). I have tried all the suggestions I can find, including checking the firewall, the no proxy server is checked, resetting cache on i

Did you try all of this:

iTunes Store loads partially or returns "Error 306" or "Error 10054"

Proxies, parental control settings and software, security or filtering software, or a bad iTunes Store cache can cause this.

To address proxies, Remove Internet Options proxy settings and connect to the Internet without a proxy.

To reset iTunes Store cache:

1. In iTunes, choose iTunes > Preferences (Mac) or Edit > Preferences (PC).
2. Click the Advanced tab.
3. Click the "Reset cache" button.
4. Click OK and see if the issue is resolved.

Adjust Parental Controls in iTunes:

1. Open iTunes.
2. Access iTunes preferences:
   1. On a Mac: From the iTunes menu, choose Preferences.
   2. On a Windows PC: From the Edit menu, choose Preferences.
3. Click the Parental Controls tab.
4. Remove restrictions on Parental Controls.
