What's up with the You Tube App for the iPhone 5? It's horrible! First of all, my 600 Favorites which I synched into my new phone from the iPhone 4, have disappeared. It seems that I have to re-install all 600; a days' work wasted at least. Worse yet, many of my favs now have a 30-second ad which I must sit through and now most of the videos no longer fill-up the screen; they are almost all shown in letterbox format with at least 80% dark. Any way I can retrieve my old iPhone 4 You Tube App? The new App is awful. Anybody like it? Maybe I'm doing something wrong.
