Question

It will be great if some can suggest weather or not to use jQuery for mobile web application for low bandwidth, also need to know if both jQuery and jQueryMobile will be needed or I can just use jQueryMobile for mobile web applications.

Thanks

jQuery Mobile is not a standalone library. It requires jQuery http://jquerymobile.com/download/

Use these minified cdn links would be good

<link rel="stylesheet" href="http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.css" />
<script src="http://code.jquery.com/jquery-1.6.4.min.js"></script>
<script src="http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.js"></script>

And jQuery Mobile team constantly work on performance with almost each release

And if you are more concerned on speed. Then jQuery Mobile has decoupled it’s library in modules so you can only use what interaction you want.

And soon jQuery Mobile is going to release a download builder for this

Download builder: In the works

Now that we’ve decoupled most of the UI widgets, we’ve set the stage
for there to be a download builder. This will let you build a custom
version of jQuery Mobile to only include the parts you need. For
example, you could just use the core files to add Ajax-based
navigation with pushState and leverage some of the touch events and
other utilities with a very lightweight build (roughly 10k). Or, you
could add in specific UI widgets like form elements, listviews, etc.
to create an optimized build. We’re aiming to have a download builder
tool launch as part of 1.0 final in some form. We’re working on a
dependency map now for all the plugins to support this tool.

Until the Download Builder is released you can always head over to Github and download the decoupled widget: https://github.com/jquery/jquery-mobile/tree/master/js
