YouTube has changed its supported API to version 3 from version 2. This has forced certain Windows Phone powered YouTube apps like MetroTube to push out an update to support the new API, or face the prospect of not working. MetroTube’s latest update to version 4.6.0.0 does allow the app to connect to the new API, which means that subscribers will be able to use the app.
In addition to MetroTube, another YouTube app for the Windows Phone platform called myTube is also going through an update (to version 2.1.0.0) so that it can use the new YouTube API. With the update, myTube now allows users to read comment reply threads, annotations and subtitles.
