Google is now pushing the Android 4.2 Jelly Bean update to the Galaxy Nexus and the Nexus 7 (or the Nexus Tablet). According to reports I was able to read, the Galaxy Nexus' Android 4.2 JB update and the Nexus 7's update is a manual update. Which means you have to download the software first before you can actually update your device. Today though, a report by PocketNow says that the Nexus 7's update is now pushing via OTA. Google has also posted on their Android Developers blog the details that Android 4.2 Jelly Bean has and what it will give your devices. Cheers!
