It started making its way to the Nexus 4 and Nexus 10 earlier today, and now it’s available as part of the Android Open Source Project. The code for the latest version of Jelly Bean, Android 4.2.1 (JOP40D) is now available for download.
As we typically point out, the source will be of little use for the average Android user, but it provides the ROM makers that many of us depend on with all the meat they need to craft custom Android builds based around the latest release. And, yes, the month of December is included.
The factory images of Android 4.2.1, which should be of a bit more use to most, will be available in the coming days, according to Android codemaster Jean-Baptiste Queru. Head on over to the Android Building group to snag the source code today.
