iOS invert left and right on screen Is there anyway to invert left and right in iOS, such that the phone looks as it would in a mirror?  (Yes all text would be backward, this is a desired effect.)  Not just a specific app that displays itself in reverse, but a system-wide effect like inverting colours.  It would probably not be a generally sought feature, one that apple would likely implement itself, but perhaps a third-party app exists?
I was looking for a similar app for video (projector issues), I came across a lot of mirror apps that were mainly for photo's and other images but some for text, others for both, as we as for inverting colours. Just search "mirror" in the app store.
