It looks like Apple might have some web apps of their own that are perhaps going live very soon. Both the Register and the Boy Genius Report indicate that the 'recent downloads' (RSS link) page of Apple's points to a few iPhone web applications. It unfortunately looks like Apple has wised up, and removed the applications from their feed, but you can at least view the screenshots in all of their glory courtesy of tBGR. Although they're in Apple's download RSS feed, all indications point to this web app directory being simple repository for online web apps. That is, not web apps that are run from your iPhone, aka widgets.
