Mirroring on iPhone 4S does not show up.
When I double click and swipe backwards to the iPod screen the airplay symbol does not show up. There are other places, like when I double click when the device is locked, that I get the airplay symbol but I only have the option to chose iPhone or apple tv. There is no switch to turn on mirroring. Help!
iPhone 4S, iOS 5.1.1
