How to switch to different Storyboard for iPhone 5?

Question

Just as an app utilizes different storyboards for iPad and iPhone, I would like my app to use a different storyboard for the iPhone 5. Since there is no option in the Info.

This worked for me - slight refinement with wrapping getting the storyboard in a function

-(UIStoryboard*) getStoryboard {   
    UIStoryboard *storyBoard = nil;
    if ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPad) {         
        storyBoard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPad" bundle:nil];
    }else{
        if ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPhone){
            // The iOS device = iPhone or iPod Touch
            CGSize iOSDeviceScreenSize = [[UIScreen mainScreen] bounds].size;
            if (iOSDeviceScreenSize.height == 480){
                // iPhone 3/4x
                storyBoard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone_4" bundle:nil];

            }else if (iOSDeviceScreenSize.height == 568){
                // iPhone 5 etc
                storyBoard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone_5" bundle:nil];
            }
        }
    }

    ASSERT(storyBoard);
    return storyBoard;
}

UIStoryboard* mainStoryBoard = [self getStoryboard];
    self.initialViewController = [mainStoryBoard instantiateInitialViewController];
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    self.window.rootViewController = self.initialViewController;
    [self.window makeKeyAndVisible];
