Hot on the heels of the Gmail app being updated for iOS this afternoon, Google has also finally seen fit to update the YouTube app for the iPhone 5. They have also added iPad support and Airplay streaming which were 2 major features missing from the version launched a few months ago.
YouTube was infamously dropped from iOS 6 and it seems the new Appstore might be on par, if not better, than the native app that was present before.
You can grab the download on iTunes here
