title: Data Protection on iOS
body: <p>If targetting iOS 4, you can use the Data Protection APIs.</p>
  
  <p>If you have 'Full' protection, does this encrypt the entire sandbox?</p>
  
  <p>Specifically, If I downloaded say a .doc file to disk programatically will this be encrypted? Or is it only encrypted if I use the NSData data protection options?</p>
