Facebook iFrame app - how to find the current city?

I am trying to migrate an old FBML application to iFrame using the new PHP SDK and GRAPH API, but I cannot figure out how to find a visitor city.

For example, in my own Facebook profile, I list both Current City and Hometown :

enter image description here

But when I try to use the following iFrame application, the location and hometown are not printed, but other data is printed, including my employers and education:

<?php

include_once 'facebook.php';

$facebook = new Facebook(array(
            'appId'  => "182820975103876",
            'secret' => "XXXXXXX",
            'cookie' => true,
            ));

$session = $facebook->getSession();

if (!$session) {
    $url = $facebook->getLoginUrl();
    print("<script type='text/javascript'>top.location.href = '$url';</script>");

} else {
    try {
        $me = $facebook->api('/me');

        print('<pre>');
        print_r($me);
        print('</pre>');

    } catch (FacebookApiException $e) {
        print("Error:" . $e);
    }
}

?>

Here is some of the data that I see for myself, the current location is not there:

Array
(
    [first_name] => Alexander
    [education] => Array
        (
            [0] => Array

                            [name] => RWTH Aachen University
                        )

                    [year] => Array
                        (
                            [id] => 143018465715205
                            [name] => 2000
                        )

                    [type] => College
                )
