Windows Phone 7 may not have support for Flash or HTML5 at launch, but it looks like you will be able to watch YouTube videos using some sort of YouTube app. A former Microsoft employee posted a picture this week which showed icons for apps in the Windows Phone 7 Market testing zone. And one of the apps is clearly labeled YouTube. The picture was later removed, but nothing ever truly disappears from the internet.
Of course, it’s also clearly labeled “Music Hub Add-On,” which may mean that it’s not a full-blown app, but rather a tool that you can use to add YouTube content to the existing Windows Phone 7 Music hub.
Other apps in the testing zone include a few games, a Yelp application, RSS reader, shopping list, stock, and weather apps.
