title: Detect the specific iPhone/iPod touch model in Javascript
body: <p>I am developing a website for Apple i* devices which uses HTML5 webkit features like transitions but I want to disable some of the fancy stuff for older/slower iPhone models like iPhone &lt; 3GS and iPod touch &lt; 3rd Gen because on those devices the transitions are too slow.</p>
  
  <p>Is there a way to detect the exact model (not just the OS/User Agent) within Javascript?</p>
