title: Update plist file in File Sharing folder - I really need advice
body: <p>I need to open a plist file located in the File Sharing folder, to add two pieces of user info to each time the app is launched; as in a new Name and Email of the user (both are of type NSString and the plist file is Dictionary).</p>
  
  <p>It then needs to save the file back to the File Sharing folder again, so that the new updated plist file can be removed at a later time via iTunes.</p>
  
  <p>If anyone could help it would be greatly appreciated </p>
