1) Changes for using of Facebook API v2.0
2) Callback URL changed to http://quickblox.github.io/BB10-Facebook-Connector/redirect?

There was issue with reading of access token from callback URL. For some reasons, Facebook passes access token in GET request parameters after hash symbol '#'. Blackberry API unable to read parameters after this symbol. So, we changed callback URl to http://quickblox.github.io/BB10-Facebook-Connector/redirect? This page just removes hash symbol and redirects to localhost with the same parameters.
Change your facebook application setting to new callback URL (on facebook site) and run this sample.
