OK, I've figured some of it out. But when I point to, say, starwars.com it doesn't take me anywhere. It just sits there spinning its tires. If I type in news.bbc.co.uk/low like you suggested, it works just fine, and fast enough, too.

Yahoo.com does nothing. T-Mobile's website is of no help whatsoever. Any help?

Edit: Oh, duh. When I enter wap.myvoicestream.com as the url in the browser, I get something.
