U.S. Tab 2 owners, your time has finally come: the Android 4.1.1 update is officially making its rounds. The 311MB update – which has been available on the UK Tab 2 for a couple of months now – recently showed up on the Wi-Fi model (GT-P5113) here in the U.S. via both OTA and Kies.
Update: Looks like the Tab 2 10.1's little brother – the Tab 2 7.0 (P3113) – is getting the update as well, also through OTA and Kies.
Of course, there's no changelog available at this point, but we all know what to expect from Jelly Bean: Google Now, Project Butter, improved performance, enhanced notifications, and more. You can see if the update is available on your device by heading into Settings > About device > Software update; otherwise, you can plug it into your PC via USB and launch Kies, which should prompt the update.
