Detecting iPhone camera orientation

Question

I\'m getting inconsistent results depending on whether I get the image directly from the camera in the callback or choosing it from the camera roll.

In the UIImag

I have tried the imageOrientation property after the picture has been taken, it's funny because I have the orientation values messed up. Up is Left, Down is Right, Left is Down and Right is Up, for example, if I hold the iPhone "Up" (the normal position) then imageOrientation is "UIImageOrientationRight".

- (void)imagePickerController:(UIImagePickerController *)picker
  didFinishPickingImage:(UIImage *)image
      editingInfo:(NSDictionary *)editingInfo {
    switch (image.imageOrientation) {
      case UIImageOrientationUp: //Left
       break;
      case UIImageOrientationDown: //Right
       break;
      case UIImageOrientationLeft: //Down
       break;
      case UIImageOrientationRight: //Up
       break;
      default:
       break;
     }
}

Currently I am using 4.1 SDK GM (xcode_3.2.4_and_ios_sdk_4.1_gm_seed) targeting for iOS 3.1
