I am considering upgrading to a Hopper system, and one of my considerations is how the iPhone app works with it. Can the iPhone app work like a remote with the Hopper? Can it also control a Joey? I currently use a video card in my PC to stream TV to my computer at work since they block the port that the Sling adapter uses. Now that the dish.sling.com website seems to be permanently down I don't have a reliable way to remotely control my receiver at home other than the iPhone app.
