I ended up using a custom subclass of UIImagePickerController to fix this (and other) issues:

#import "SMImagePickerController.h"

@implementation SMImagePickerController

void hideFlipButtonInSubviews(UIView *view) {
    if ([[[view class] description] isEqualToString:@"CAMFlipButton"]) {
        [view setHidden:YES];
    } else {
        for (UIView *subview in [view subviews]) {
             hideFlipButtonInSubviews(subview);
        }    
    }    
}    

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];

    hideFlipButtonInSubviews(self.view);
}    

@end

You should be able to create an empty button inside an overlayview that you float on top of the flip camera button. I hacked the code below to test and it seemed to work. Give it a try.

UIView *cameraOverlayView = [[UIView alloc] initWithFrame:CGRectMake(screenSize.width - 100.0f, 5.0f, 100.0f, 35.0f)];
[cameraOverlayView setBackgroundColor:[UIColor blackColor]];
UIButton *emptyBlackButton = [[UIButton alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 100.0f, 35.0f)];
[emptyBlackButton setBackgroundColor:[UIColor blackColor]];
[emptyBlackButton setEnabled:YES];
[cameraOverlayView addSubview:emptyBlackButton];

cameraUI.allowsEditing = YES;
cameraUI.showsCameraControls = YES;
cameraUI.delegate = self;

cameraUI.cameraOverlayView = cameraOverlayView;
