Microsoft already testing third-party applications in the Windows Phone 7 MarketPlace: YouTube, Yelp

It should come as no surprise that Microsoft has already started to populated the yet unreleased Windows Phone 7 Marketplace with a couple of third-party applications alongside some in-house apps. I already saw this 2 days ago when I was at the Microsoft Campus for some WP7 development work but Justin Angel from Vertigo Software actually decided to take a screenshot of the Zune software and post it on Twitter a couple of hours ago. As you can see in the shot above Microsoft has already released the in-house applications that we saw in the Channel9 video this week and a few third-party apps are already up for grabs. (like Yelp, Hexic etc) Interestingly there’s a YouTube extension to the Music & Video hub which should make everybody happy. WP7 users will apparently be able to directly access Youtube hosted videos via the Zune Hub.
