I'm pretty sure there is a typo here

shouldn't the is_mobile_device line read?
$is_mobile_device = ($is_wireless || $is_tablet);

$is_wireless = ($requestingDevice->getCapability('is_wireless_device') == 'true');
$is_smarttv = ($requestingDevice->getCapability('is_smarttv') == 'true');
$is_tablet = ($requestingDevice->getCapability('is_tablet') == 'true');
$is_phone = ($requestingDevice->getCapability('can_assign_phone_number') == 'true');
$is_mobile_device = ($iswireless || $istablet);

You're correct - thanks for the good catch! We'll get it updated soon.
