title: Make iphone/smartphone vibrate from website, is it possible?
body: <p>So im buiding a little quiz game using php, jQuery etc. 
  I have maded it so each player uses his or hers smartphone as a "buzzer" button. And the i was wondering if it is possible to make the phone vibrate to give the user a nicer feedback of pressen the button.</p>
  
  <p><a href="http://davidwalsh.name/vibration-api" rel="nofollow">I found a vibrate API</a> but iOS is not supporting it (i have an iphone to test it)</p>
  
  <p>It is the only thing i could found about it, someone know something else?</p>
