Google announced Tuesday that it has started to roll out Android 4.2 Jelly Bean to the Galaxy Nexus and existing Nexus 7 tablets. Until now, the operating system was only available from new Nexus 10 and Nexus 4 devices sold directly by the firm. It's unclear if the Galaxy Nexus on Sprint and Verizon Wireless are receiving the update now, too, but we're guessing that there are still a few weeks (hopefully not months) of carrier testing first.

Android 4.2 Jelly Bean adds a host of new features, including a redesigned lock screen, a new 360-degree photo taking app, multiple user support on tablets, expandable and actionable notifications, and an Android experience that's smoother than ever.
