Whenever an official version of the Android mobile operating software is released, unofficial ones always follow swiftly behind. An example of the latter is the CyanogenMod ROM, which has recently released an Android 4.2 (Jelly Bean) update for the Google Nexus 4. The file was released by XDA KonstantinKeller and developer reports indicate all features, with the exception of Themes and Gesture Typing (since this is not Android Open Source Project), are working.
