iOS screen size

[Dan Friedman]

Stupid Question (I should know this!)...   Why in my iOS app not scaled to the device?   I am getting black bars at the top and bottom of the device.   I thought this once had to do with the splash screens, but changing the "Launch Image" doesn't seem to have any effect.  I don't recall having to set fullscreenmode, but that seems to have no effect either.
