title: Possible to use the native facebook app to log into a mobile html5 app? On the iPhone
body: <p>I'm trying to have my html5 site open the native iPhone Facebook app to authenticate users.</p>
  
  <p>The site currently uses OAuth 2 on the server side - so it redirects everyone to the web version of Facebook. This is a problem because I dont want to force people to log in on a tiny keyboard.</p>
  
  <p>Can you get the html5 app to open in Safari and authenticate through the native FB app?</p>
  
  <p>If this is not possible with Facebook is it possible with Twitter apps? What is the experience like on android?</p>
  
  <p>I do know that you can authenticate between a native iPhone app and the native Facebook app.</p>
