GUI (using GUI Builder) in landscape mode

Hi,

I've been trying to figure out how to get my GUIControls displaying in landscape mode on the iPhone and I've been digging through the forums and documentation for an explanation on how to do this. Is it possible to have my GUI Controls display in landscape mode? (i.e. if I design a GUI through GUI Builder, is it possible to enable a flag to have the GUI rotated so that it appears correctly in Landscape mode?)

There's probably a very simple way of doing this but I've been unable to figure out how to do this.

Thanks in advance!
