title: Multi-language HTML5 application
body: <p>I'm developing a HTML5 application with CSS3 and jQuery.</p>
  
  <p>I have some text that I want to show in user language. Do you know how I can do that?</p>
  
  <p>This application will run on Blackberry Playbook and on others mobile devices.</p>
  
  <p>I don't know how to get user OS language, or where I must put my localize strings, etc.</p>
  
  <p>Any clue? </p>
