Note:
In order to use the leak, you need an Android device with a maximum resolution of 1280x768 and the ability to completely uninstall your existing Facebook app. This is important, as the leaked APKs are re-signed and can't just be installed over the top of an existing installation. This will automatically exclude some devices which have Facebook installed in the base ROM. If you're on a Nexus device you're good! Even if you do have Facebook in ROM, provided you are rooted there are workarounds.
