Machintosh News Network is a popular Apple news site with a very active forum. macnn also has two mobile editions. The one at mobile.macnn.com has summaries of the main site's news stories in a small screen friendly single column layout. It's a big page, about 560 KB, and the summaries link to the full web versions of articles making it best suited to the iPhone and other full-web mobile browsers.There's also the "classic" mobile version (macnn.com/avantgo) which at about 150KB is still too big for the built browsers of mass-market feature phones. But if you're reading macnn you have an iPhone, right?
