Is there a documented way to set the iPhone orientation?

by

This is long after the fact, but just in case anybody comes along who isn’t using a navigation controller and/or doesn’t wish to use undocumented methods:

UIViewController *c = [[UIViewController alloc]init];
[self presentModalViewController:c animated:NO];
[self dismissModalViewControllerAnimated:NO];
[c release];

It is sufficient to present and dismiss a vanilla view controller.

Obviously you’ll still need to confirm or deny the orientation in your override of shouldAutorotateToInterfaceOrientation. But this will cause shouldAutorotate… to be called again by the system.
