YouTube today revamped their mobile website for WebKit browser-equipped devices, specifically the iPhone and devices running Google’s Android OS. The new site uses HTML5 for video viewing which allows mobile browsers to view YouTube videos without the need for flash capabilities. With the new version of YouTube’s mobile site, even the native Android YouTube application seems unnecessary and outdated, not to mention the iPhone’s app, which hasn’t seen a significant update since it’s introduction on the original iPhone. The new mobile version of YouTube also allows high quality video to stream over 3G, whereas the iPhone’s YouTube application limits this functionality to WiFi connections. The mobile site also allows users to subscribe to user’s YouTube channels from the browser, as well as like/unlike individual videos.

Check out the video of YouTube’s new mobile site in action on both the iPhone and Nexus One after the break, and feel free to give m.google.com a looksy if you have one of those newfangled iPhones or Android handsets.
