The Asus Transformer Pad TF300 will become the first non-Nexus device to be upgraded to Android 4.2 Jelly Bean. Asus has announced that the update is rolling out over-the-air to users in the United States today, while those in other regions should start receiving it by the end of the month.

A couple of days ago, Google started rolling out the Android 4.2.2 Jelly Bean update for the Galaxy Nexus, Nexus 7 and Nexus 10, with the Nexus 4 joining the list today. The update is being rolled out over-the-air, so it can take up to a couple of weeks or more for it to be available on your Nexus device.

If you have root access, you can easily install the update manually. If not, you can try to pull the update manually from Google’s server. Depending on your region and your luck, you might just be able to manually initiate the OTA update on your Nexus device. Here are the steps you’ll need to give it a go.

Google began rolling out its Android 4.2.2 Jelly Bean update earlier this week, and it looked as though the software would bring nothing more than a few important bug fixes. But after used their devices after upgrading, Nexus owners have begun to notice some changes throughout the OS.

In addition to better download notifications, Android 4.2.2 brings some changes to the Quick Settings pane, and a number of new notification sounds.

As expected, Google has begun rolling out its Android 4.2.2 Jelly Bean update to a number of Nexus devices, including the GSM Galaxy Nexus, the Nexus 7, and the Nexus 10. The software comes with the “JDQ39” build number, and it delivers fixes for a number of key issues — most notably a Bluetooth streaming bug.

Now, widgetized. See what we did there?

Hey, remember that Google Now thing that we mentioned earlier this morning? Well, it turns out that there’s gonna be a widget, too, as revealed in the support documentation for the new Nexus 4 and 10, as well as the Galaxy Nexus, Samsung’s entry in the series.
