widgets in footer?

Here is complete code that runs this sidebar from sidebar-footer.php template:

<?php if ( is_active_sidebar( 'first-footer-widget-area' ) ) : ?>
                <div id="first" class="widget-area">
                    <ul class="xoxo">
                        <?php dynamic_sidebar( 'first-footer-widget-area' ); ?>
                    </ul>
                </div><!-- #first .widget-area -->
<?php endif; ?>

You can move this snippet around, but it might break styling. Also Twenty Ten is often upgraded with WordPress and by itself and you will need to create child theme for it so your changes stick.

I’d first try to move widgets with CSS or maybe register separate sidebar if something specialized is needed.
