title: Automatic update new version of symbian application
body: <p>I have a Qt Symbian application. I didn't publish it via Nokia OVI store. I'm distributing the app in my own website. What I need to know is, If I released a new version of my app, the user should be able to automatically download the new version.</p>
  
  <p>I mean, whenever he/she launch the app, he should be informed about the release of the new version (if an update is available). And then he may have the option to install the update or skip it.</p>
  
  <p>How to achieve this....? </p>
