It there any way to output my iPhone to my iPad? So the display on my iPhone is mirrored on the iPad. I have an unlimited data plan and use my Slingbox to watch tv on my iPhone. I have used tvout to output on a tv. I would like to be able to use my iPad as the "tv" if you will, and have my Slingplayer on the iPad. I have tethered and used the sling box on my iPad but use twice as much data. I have an unlimited data plan and am worried about being billed for tethering.
