title: iPhone image upload in background
body: <p>I'm writing an app with an image upload feature. Right now I'm using NSURL POST like: <a href="https://stackoverflow.com/questions/125306">125306</a>.</p>
  
  <p>When the app is closed as far as I can tell all of the uploads abort and the threads die.  Is there<br></p>
  
  <p>1) a way to make these upload threads persist when the app is no longer in the foreground? </p>
  
  <p>2) an iPhone OS service that will accept requests to queue a job and run it in a mode managed by the OS?</p>
