Browser Proxy Redirect annoyance

Why does my Blackberry think that it is in Waterloo, Ontario, Canada?

No, wait, I'll answer that for you. The Web Browser (and at least one or more of the other internet applications) uses a proxy server for its IP address. That proxy is in Waterloo, home of R.I.M.. This is deliberate, and as far as I know, I can't change it. No matter where I am on the globe, no matter what service provider I use, my Blackberry thinks it's in Waterloo.

So, the real question is, why does R.I.M. insist that the internet connections be proxied? Idiotic! So, for example, when I try to use a web service that finds my location by IP (say, a map provider) and, it gives me all sorts of local hits for good restaurants in my area, "my" area turns out to be ... southern Ontario? Right, I'm sitting at Jazz Fest in New Orleans and I want my default location to be right next door to the Welland Canal. Don't get me wrong, I think St. Catharines and Niagara on the Lake are quaint an' all, but ... jeepers. Make it stop.
