Customize template for registered users

Hi-

In the last version of mobile joomla, I was able to show a position to guests and hide it from registered users through the following code.
$user = &JFactory::getUser();
if($user->guest){
if($modulepos && $this->countModules($modulepos) > 0)
{
$MobileJoomla->loadModules($modulepos);
}}

now, I can't echo the $user. Appreciate some help.

Should work. Check that $modulepos is assigned above this code.

worked fine before the last upgrade. now if you echo $user nothing happens. You can check it out at vidons.com on iphone.

$user is an object, so to print it out you should use print_r($user); or var_dump($user);
