jQuery Mobile is not a complete library, you will need jQuery 1.6.4.
jQuery Mobile is lightweight and you can get a smaller version that will be smaller in size. You should also look at using CDN for your library, for example:
<script src="http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.js"></script>
Instead:
<script src="jquery.mobile-1.0.1.min.js"></script>
If you did not know, CDN means the content delivery network, that is, the JQ library is located in another place, for example, on a Google server or jQuery, and delivered to your application. Thus, if the user has already downloaded / used the library before while browsing other websites, they will not have to download the library again. The benefits of this are better caching and lower latency.
