Adding Loop To single.php

First of all, sorry that I’m posting too much silly questions on this forum, cuz I’m new to wordpress, and trying to customize my site as much as I could. Okay so today I found about post formats (video, link and all)

I want to add following loop element (or whatever it really is) to my single.php:

<?php elseif ( ( function_exists( 'get_post_format' ) && 'link' == get_post_format( $post->ID ) )  ) : ?>  

        <div id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
            <h2 class="entry-title"><a href="<?php echo get_the_content(); ?>" title="<?php printf( esc_attr__( 'Permalink to %s', 'twentyten' ), the_title_attribute( 'echo=0' ) ); ?>" rel="bookmark"><?php the_title(); ?></a></h2>
        </div>

Here is my single.php file, tell me where to add above code:

<?php get_header(); ?>

<div id="content" >

<?php if (have_posts()) : ?>
<?php while (have_posts()) : the_post(); ?>

<div class="post" id="post-<?php the_ID(); ?>">

	<div class="title">
		<h2><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><?php the_title(); ?></a></h2>
	</div>

	<div class="postmeta">
		<span class="pmet">Posted by <?php the_author_posts_link(); ?>  on <?php the_time('M - j - Y'); ?> </span>
	</div>
	<div class="entry">
		<?php the_content('Read the rest of this entry &raquo;'); ?>
		<div class="clear"></div>
		<div class="pagelink"><?php wp_link_pages(); ?></div>
	</div>

	<div class="titlemeta clearfix">
		<span class="categori"> Categories: <?php the_category(', '); ?>   </span>
	</div>

<nav id="nav-single">
                        <span class="nav-previous"><?php previous_post_link( '%link', __( '<span class="meta-nav">←</span> Previous', 'twentyeleven' ) ); ?></span>
                        <span class="nav-next"><?php next_post_link( '%link', __( 'Next <span class="meta-nav">→</span>', 'twentyeleven' ) ); ?></span>
                    </nav><!-- #nav-single -->

</div>

<?php comments_template(); ?>
<?php endwhile; endif; ?>

</div>

<?php get_sidebar(); ?>
<?php get_footer(); ?>

Thanks!
