iphone landscape slash screen shows in portrait orientation

My game has play default screen orientation set to landscape left and I have a 480 x 320 splash screen. It is being squashed and displayed in portrait mode. In the game I put it on a GUITexture ans it display fine. Any idea how to get the original splash screen to display in landscape more.

The spashscreen doesn't listen to orientation so just rotate it 90 degrees in a painting program so size is 480x320, not 320x480.

You can have a high resolution default screen, make a 1024x1024 image, put your 1024x768 main content at the top of the image and then rotate it (CW or CCW depends of your app orientation). This works fine for me.
