A tool used as a proxy service is the Google Wireless Transcoder. This service was designed to make web pages viewable on mobile phone browsers. It will download a destination site's web page, including images, and rework the entire page, on the fly, to fit into an average cell-phone's screen space.
To try it out, go to( google.com/gwt/n ) with your blackberry browser and enter the url you'd like to view. You'll quickly see that most of the page formatting has been stripped out, leaving a very simple, single-column page. You'll also notice that all the images are scaled down to mobile phone optimized size. It's a bit of a downside, but google is actually downloading and sending the scaled versions from a google server. So, if you're on a blacklisted site, you'll still be able to view images - they'll just be smaller than usual.
On the plus side 99% of MySpace templates look better using the Google Wireless Transcoder.
