Today, Google rolled out the new YouTube Mobile Web App to the world. The app is very fast, and is much more feature-packed than the native application on the iPhone. Similar to the design revamp that Google instated on the Desktop Version of the YouTube website, the iPhone Web App sports an all new design, as well as many new useful features. These features include: quicker video loading, better video page management, better channel pages, better browsing features, better management of playlists/subscriptions/favorites, and better stability of the site overall. If you haven't already--grab the web app! The Link is below. Enjoy.
