Magento Add new Fields In Customer Address?

Question

I want to add new field Title. This field is a Dropdown and I give value like this.

$attributes = array(
'jobtitle'           => array(
    'label'    => 'Title',
    'backend_type'     => 'varchar',
    'frontend_input'    => 'select',
    'is_user_defined'   => 1,
    'is_system'         => 0,
    'is_visible'        => 1,
    'sort_order'        => 140,
    'is_required'       => 1,
    'multiline_count'   => 0,
    'option'            => array (
        'value' => array(
            'Mr' => array('Mr'),
            'Mrs' => array('Mrs'),
            'Ms' => array('Ms'),                                               
            'Miss' => array('Miss'),                                               
            'Dr' => array('Dr'),                                              
            )
    ),
    'validate_rules'    => array(
        'max_text_length'   => 255,
        'min_text_length'   => 1
    ),
),
);

foreach ($attributes as $attributeCode => $data) {
    $attribute = $eavConfig->getAttribute('customer_address', $attributeCode);
    $attribute->setWebsite($store->getWebsite());
    $attribute->addData($data);
        $usedInForms = array(
            'adminhtml_customer_address',
            'customer_address_edit',
            'customer_register_address'
        );
