title: How to vibrate BlackBerry though code?(Java)
body: <p>Here is what I'm trying to do ..<br>
  Whenever event occurs, device should vibrate for couple of seconds.</p>
  
  <p>I tried to use 
  <code>
  Display.getDisplay(this).vibrate(2000);
  </code></p>
  
  <p>It did not vibrate, while testing on device<br>
  Even tried it with device profile was set to Vibrate(Active) </p>
