This is first EPL app on the platform and it’s a great app but better read some official and unofficial press releases as there is enough said about this already:

As part of development works we also found that there has been a lack of decent Facebook API library for BB10 so we have created one and shared it on GitHub which has also been shared to BlackBerry developers community (thanks to Brian Zubert and his team). All BlackBerry 10 developers please feel free to use the library. It is not tied with QuickBlox Users API so you may use it in any project even if it doesn’t use QuickBlox.
