title: Change Phonegap User Agent
body: <p>My Phonegap application is allowed to browse to some external sites that also use the Phonegap API.  Currently I am conditionally including the Phonegap javascript based on what platform you are on (Android, iOS, etc).  However, I can't tell the difference between Phonegap applications and the regular browser on a mobile device.  Is there a way to change the user agent in my Phonegap app to give my server a hint about this?</p>
  
  <p>Most interested in the iOS solution to this.</p>
