title: FB.login(): Unsupported Browser IE Mobile
body: <p>I am using the Facebook Javascript SDK in an .NET MVC mobile website. All of a sudden (since a few days) FB.login() doesn't seem to work on Windows Phone 7.8 phones. I get an error "Unsupported Browser: IE Mobile does not support this feature...".</p>
  
  <p>It does work on mobile browsers on Android and IPhone. </p>
  
  <p>Any ideas? </p>
  
  <p>Thanks!
