I know this is probably a dumb questions but I've looked around and I'm still completely lost. What is the VPN option on the ipod touch used for? I don't even know what it is (other then virtual privet network) but that means nothing to me at this point. How can I take advantage of the feature? I saw that in the beginning that some had the option some didn't or so it seemed. So if you could be kind enough to give me the run down (Im sure it would be appreciated by many others as well) I would really appreciate it. Thanks in advance.
