title: How can an app enable "Allow Automatic Updating" in the Android market
body: <p>I noticed that some apps like Google Maps, Facebook for Android etc. (all preloaded BTW), have their "Allow Automatic Updates" check box checked without me doing so.</p>
  
  <p>Is it possible for preloaded apps only?</p>
  
  <p>How can I achieve that with my app?</p>
