Get Widget Title

Hi all, I am trying to register my own sidebar to modify the format of the outputted html, like so:

<?php
if ( function_exists('register_sidebar') )
    register_sidebar(array(
    'before_widget' => '<div id="%1$s" class="widget entry %2$s">',
    'after_widget'  => '</div>',
    'before_title'  => '<h2 class="widgettitle">%1$',
    'after_title'   => '</h2>' ));
?>

That all works great. However, what I really wanted to do was to obtain the Title text associated with the current widget. That is for example “Archives” or whatever the user has changed that to.

I have tried to chug through some of the wp source code and my php knowledge and wp knowledge leaves me a little wanting.

So my question. Is it possible to obtain this information and reoutput it in the code above, for example:

<?php
if ( function_exists('register_sidebar') )
    register_sidebar(array(
    'before_widget' => '<div id="%1$s" class="widget entry %2$s">',
    'after_widget'  => '</div>',
    'before_title'  => '<h2 title="%title$" class="widgettitle">%1$',
    'after_title'   => '</h2>' ));
?>

Thanks
