Different behaviour for next and previous links

Hi

I have a small problem to find the correct if-statement to show different behaviour for the next and previous link in single.php.

For all categories which is showned beside category id=22 I want this:

<span class="nav-previous"><?php previous_post_link( '%link', __( '<span class="meta-nav">&larr;</span> Previous', 'twentyeleven' ), FALSE, '22'); ?></span>
						<span class="nav-next"><?php next_post_link( '%link', __( 'Next <span class="meta-nav">&rarr;</span>', 'twentyeleven' ), FALSE, '22'); ?></span>

which works fine
but for category with id=22 I want this:

<span class="nav-previous"><?php previous_post_link( '%link', __( '<span class="meta-nav">&larr;</span> Previous', 'twentyeleven' ), TRUE, '22'); ?></span>
						<span class="nav-next"><?php next_post_link( '%link', __( 'Next <span class="meta-nav">&rarr;</span>', 'twentyeleven' ), TRUE, '22'); ?></span>

So which if-statement should I use in single.php to get this to work?
