Here is the latest Keyboard of mine. This one is based on the Leaked Android 4.2 JOP24G Jelly Bean Build.
Yes that's right from the Nexus 4 leak. I have tested it on Jedi Mind Trick v9 so I assume X and the newest one it would work with as well as any TouchWiz or AOSP roms based on Android 4.0.1 and newer.
