title: How do I secure cross domain calls in PhoneGap, Cordova?
body: <p>I am writing my first secure service that PhoneGap needs to access.</p>
  
  <ul>
  <li>What data format is the most secure or appropriate to return?</li>
  </ul>
  
  <p>I'm mostly interested in returning JSON, JSON-P, or OData but I can use XML if it's more secure.</p>
