Using Cocoa Touch Tutorial: Extract Address Book Address Values on iPhone OS

Question

I've followed the following tutorial, in the simulator it works great, however on my phone when select the address, Google maps launchs, I think I've fried my brain on this. I am using this in conjunction to a NavBarContolloer Any help would be great.

Here's the code:

#import "RootViewController.h"
#import "SecondViewController.h"
#import "ThirdViewController.h"
#import "FourthViewController.h"


@implementation ThirdViewController

@synthesize fourthViewController;
@synthesize firstName;
@synthesize lastName;
@synthesize addressLabel;

-(IBAction)switchPage:(id)sender
{
    if(self.fourthViewController == nil)
    {
        FourthViewController *fourthView = [[FourthViewController alloc]
                                          initWithNibName:@"FourthView" bundle:[NSBundle mainBundle]];
        self.fourthViewController = fourthView;
        [fourthView release];
    }

    [self.navigationController pushViewController:self.fourthViewController animated:YES];
}

    ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init];

    // showing the picker
    [self presentModalViewController:picker animated:YES];
    // releasing
    [picker release];
}

    // setting the number

     if you do not set a number for a contact it will probably
     crash

In

-[ABPeoplePickerNavigationControllerDelegate peoplePickerNavigationController:shouldContinueAfterSelectingPerson:property:identifier:]

you need to return NO in order not to launch Google Maps. Returning YES would continue with the default action, which on the device is launching Google Maps.
