The fine folks at Sling were kind enough to give TiPb a demo of their soon-to-be submitted to the Apple iTunes App Store SlingPlayer Mobile for iPhone client and it looked all shades of sweet. In addition to great H.264 quality and video overlays, they went all the way and implemented "swipe to change channels". We. Want. This. Now.
Watch the video for the full on demo, and let us (and Sling, and Apple) know what you think.
