Last friday, one week before the official launch of the much anticipated iPhone, Apple debuted a 20-minute guided tour of the next-gen phone on its Web site.

The video is thoroughly informative including minutiae such as the volume and power buttons. The exciting content, however, is watching the touch screen in action (flipping through album covers, changing userbar buttons, rotating the iPhone horizontally and vertically–hm, perhaps I’m easily amused). The Web browsing capability looks especially promising. Users can zoom in and out and move around the page with a swish of the finger. Of course, this being a YouTube world now (or at least a YouTube year), there is an entire section on utilizing YouTube content with the phone.

The iPhone blasts off June 29 (as if you and your early adopter buddies didn’t already know that).
