That WP7 third party apposphere just got a nice boost from SlingPlayer, which has announced its intention to soon be present and accounted for on Microsoft's new platform. What we've got today is a quick teaser video showing off the live TV streaming capabilities under Windows Phone 7, along with the remote set-top box controls and a switch for turning the stream's quality up. Sling Media promises up to four times the resolution available on previous Windows Mobile versions and draws a launch window around the woolly concept of "soon." See the moving pictures after the break.
