title: Need to convert my HTML5 based web application into a mobile app which will target all mobile devices
body: <p>Is it possible to convert my existing HTML/jquery.js website into a mobile app that targets all device (iPhone, Android, Blackberry, etc.). Below are the points I can think of. Please correct me if I'm wrong.
  Add jquerymobile.js and change the css style (based on the device which is accessing your site).</p>
  <p>What all points should I consider while converting my existing desktop based website into a mobile one. Or should I start creating a mobile website (MVC4 mobile website) from scratch? If that is the case then I have to maintain 2 code bases (1 for desktop and 1 for mobile) which I don't want to do.</p>
