UIAlertView won't rotate to landscape even with applicationDidFinishLaunching call

Question

I am trying to use UIAlertView on my landscape right (home button on the right) app but it is showing up in portrait orientation. I have tried putting:

[[UIApplication sharedApplication] setStatusBarOrientation: UIInterfaceOrientationLandscapeRight animated: NO ];

in applicationDidFinishLaunching, but it doesn't work. Are there any other usual suspects to what might be causing this? I am setting the orientation through my plist file currently.
