This is a post which does not contain any information I've gained from working here: in fact, I _haven't_ gained any information on this subject by working here. I'm Support, not Product.

With that said...

Before working here, I heard that Fox actually locks the current location + 2G (which is the reason for the 2G limit). Is this what you're talking about up above, Robert?
