There should be no problems at all obtaining a copy of jQuery Mobile, but anyway, here is a quick walkthrough to get all the mobile development enthusiasts out there started.
The fastest, easiest way to include jQuery Mobile into your website is by downloading one of the CDN-hosted versions that the jQuery Mobile project provides, which include images as well.
You can choose from two types of packages to download: one is uncompressed and for debugging purposes only (very large size); the other one is the minified and gzipped set of files which are ready to deploy.
Note
jQuery Mobile 1.0 Alpha 2 requires jQuery 1.4.4, which can be download from http://docs.jquery.com/Downloading_jQuery.
CDN-hosted JavaScript can be obtained from:
jquery-mobile-1.0a2.js
(Uncompressed, 102KB, useful for debugging) http://code.jquery.com/mobile/1.0a2/jquery.mobile-1.0a2.js.jquery-mobile-1.0a2.min.js
(Minified and gzipped, 13KB, ready to deploy) http://code.jquery.com/mobile/1.0a2/jquery.mobile-1.0a2.min.js.
CDN-hosted CSS can be downloaded from:
jquery-mobile-1.0a2.css
(Uncompressed, 49KB, useful for debugging) http://code.jquery.com/mobile/1.0a2/jquery.mobile-1.0a2.css.jquery-mobile-1.0a2.min.css
(Minified and gzipped, 6KB, ready to deploy) http://code.jquery.com/mobile/1.0a2/jquery.mobile-1.0a2.min.css.
A Zip file is also available for those willing to host the files themselves. The Zip file contains both versions of the JavaScript library (uncompressed and minified), all the required images, and CSS instructions, and can be downloaded from the following URL:
jquery-mobile-1.0a2.zip
(Zip file: JavaScript, CSS, and images) http://code.jquery.com/mobile/1.0a2/jquery.mobile-1.0a2.zip.
If you have chosen to make use of the CDN-hosted versions, the following couple of lines of code can be used to link to the libraries and the CSS stylesheet needed to set up jQuery Mobile:
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.0a2/jquery.mobile-1.0a2.min.css" /> <script src="http://code.jquery.com/jquery-1.4.4.min.js"></script> <script src="http://code.jquery.com/mobile/1.0a2/jquery.mobile-1.0a2.min.js"></script>
