How can I display site title as <h2> tags on sub pages/posts?

Hi

wordpress 3.5
Theme Socrates 3.0+
Have All in one SEO installed

I was checking my site and discovered that all the pages/posts on my blog have the site title in h1. That is bad for SEO. Only on index page I want it to be in h1.

I wonder how I can get the site title to be in h2 on subpages/posts?

I've also been looking into manually change the header.php for the theme but I got an error while doing so:
Parse error: syntax error, unexpected $end in /mydomain.com/wp-content/themes/socrates/header.php on line 207

Here is the part in header.php I changed:

<?php } else {
if (is_home())
{ ?>
<div class="titleText socshadow" style="margin-bottom:-5px;font-weight:bold;"><h1><a href="<?php bloginfo('url'); ?>"><?php echo stripslashes($header['titleText']); ?></h1></div>
<div class="descText socshadow"><?php echo stripslashes($header['descText']); ?></div>
<?php } else { ?>

Thank God I took backup of the file before I edited it

I have attached the file I changed here, my changes are at about line 161

Anyone knowing how to set the site title in h2 on sub pages/posts?
