If those of you on Big Blue have been jealous of The Now Network's Jelly Bean offerings to the LG Optimus G, today's your lucky day. AT&T just announced the official Android 4.1 (4.1.2 to be exact) update for its variant of the LG flagship, complete with Google Now, expandable notifications, and all the other goodies that one expects to come with the full OS update.

The OTA also enables the ISIS Mobile Wallet, which allows users in Austin and Salt Lake City to test the waters with the new mobile payment system. To give it a shot, however, users need to head to the nearest AT&T location to get a "special SIM" that is required to use the app.

The 366 MB update is rolling out now, and can be pulled down by heading into Settings > About phone > Software update > Update now while on a Wi-Fi connection. Have fun!
