How do you get a persons phone number from the address book?

The “identifier” argument does not hold the CFIndex of the record touched. The method I use to tell which phone number a user selected is this:

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier
{
    if (property == kABPersonPhoneProperty) {
        ABMultiValueRef multiPhones = ABRecordCopyValue(person, kABPersonPhoneProperty);
        for(CFIndex i = 0; i < ABMultiValueGetCount(multiPhones); i++) {
            if(identifier == ABMultiValueGetIdentifierAtIndex (multiPhones, i)) {
                CFStringRef phoneNumberRef = ABMultiValueCopyValueAtIndex(multiPhones, i);
                CFRelease(multiPhones);
                NSString *phoneNumber = (NSString *) phoneNumberRef;
                CFRelease(phoneNumberRef);
                txtPhoneNumber.text = [NSString stringWithFormat:@"%@", phoneNumber];
                [phoneNumber release];
            }
        }
    }

    [self dismissModalViewControllerAnimated:YES];
    return NO;
}
