Putting the "+" button on All Contacts

Question

When I call

-(IBAction)getContact {

    ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init];
    picker.peoplePickerDelegate = self;

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

All Contacts appears with the Cancel button on the right. What I would like is for the user to also add much like Contacts.app. So I need to put the "+" button on the left. How do I do that?

Or how do I get the picker to come up like the Contacts.app, have the '+' showing on the right where the Cancel is now?
