title: Facebook in-app showing up in different language
body: <p>I have a very bizarre issue with the facebook-ios-sdk.  Client is complaining about the in-app dialogs showing up in Spanish, when neither their Facebook nor phone is set for spanish.  This is happening across multiple devices and multiple users/accounts.</p>
  
  <p>The Facebook SDK should be pulling the user's language/locale preferences from NSLocale, correct?  Is there a way to set or test this?  Is there some way the language is being set in the HTTP Header Requests for the in-app dialog incorrectly?</p>
  
  <p>(using SSO if it makes a difference)</p>
  
  <p>Thanks,</p>
