Jailbroken AppleTV and proxy settings
We've just purchased an AppleTV here for use at the school I work at - unfortunately before purchasing it wasn't researched that we couldn't add proxy settings directly to it in it's default form.
I've read around the web and have found out how to add proxy settings via /private/var/preferences/SystemConfiguration/preferences.plist but unfortunately I can't work out how to actually edit it to make it work using our proxy.
Could anyone give me a hand here and tell me if I'm missing something very obvious? I've found two locations that refer to proxies and I have no idea which one I would edit or how I would edit it.
Thanks in advance!
