Carlos:
jquery is called from the head section of my theme and/or plugin theme.
search your directories for something like....
<script type='text/javascript' src='https://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js></script>
Then get change the entry to Google's current version.
if you don't find where it is loaded into your theme, you can always hardcode that like into the head section of your template.
