title: Can one continuously poll the iphone for GPS coordinates?
body: <p>The iPhone app I'm thinking of developing needs to be able to report the GPS coordinates to a backend service at regular intervals. It's my understanding that the iPhone currently does not support background applications, which means that there's no way for me to leave an app running in the back and sending coordinates to a server.</p>
  
  <p>What's a reasonable workaround? Since push notifications are available on the iPhone, can the server actually pull the phone for any kind of data? While not ideal, that would still update the backend with the necessary information.</p>
  
  <p>Thanks!</p>
