The iOS apps was removed recently from the Apple app store because it wasn't compatible with iOS6, but even then, I don't believe it was compatible with anything before a 2011 TV. As far as one-remote solutions go, many exist.
I have a PN50B860 and I'm looking for an ipad app I can use to turn on my TV. Does it exist? I want something simple. I have an app that works with my Integra AVR (oremote), but I can't turn on the TV with that app, although It will turn on my Panasonic blueray.
Is there an app for that, or is there a way to turn on my TV with oremote? Any help would be appreciated.
