I have done this: How to develop or migrate apps for iPhone 5 screen resolution? i.e. added the Default-568h@2x.png file.
My app still launches with the black bars top and bottom. It launches with the Default.png launch image, not even the Default@2x.png.
I'm using story board for layout of the screens, not xib. It's a pretty basic series of screens, table view driven.
What the hell have I done wrong?

Deleting the images, and re-adding them along with cleaning the project before rebuild was the answer as suggested by pcholberg and Renjith
