At some point (probably right after the installation), you'll want to update these themes to use the latest versions of the jQuery Mobile library. Some are still using the beta version. The process is actually pretty straightforward. All you have to do, is find the header sections of the templates in question, and update the references to the jQuery Mobile CSS, JavaScript, and probably the core jQuery library.
For the jQMobile WordPress theme, you only need to change two files. In the header.php file, find the following:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script> <link rel="stylesheet" href="http://code.jquery.com/mobile/1.0a1/jquery.mobile-1.0a1.min.css" /> <script src="http://code.jquery.com/jquery-1.4.3.min.js"></script> <script src="http://code.jquery.com/mobile/1.0a1/jquery.mobile-1.0a1.min.js"></script>
