Good news for people who love downloading iOS updates -- just hours after Google refaced its Gmail for iOS app, here comes another heavyweight in YouTube. The standalone app is now fully optimized for use with iPad and the iPhone 5, and perhaps the biggest gift of all is the addition of AirPlay streaming for videos. Other updates include the ability to tap a logo to open one's Guide of channels, the ability to add / remove videos from your playlists, clickable links in video descriptions and improved accessibility with VoiceOver. Feel free to hit the source link to dive in, and let us know how it turns out in comments below.
