I got Jelly Bean on my HOX 2 days ago, on 12 December here in Luxembourg.
I have the international HOX version with TEGRA
My software number changes from yours and is 3.14.401.27 compared to your 3.14.709.16, which is probably why I have all the battery features except the "Application Monitor" function. Also, when charging, it doesn't show the percentage at the top left next to the "Power saving" icon in the notification bar. I find the keyboard needs a little getting used to. Especially the fact that you have to push the < button to make the keyboard disappear. But it will probably work for me in the end. Other than that, I'm excited to be able to use Google Now and would like to get the new camera feature of 360 degrees panoramic, which I can't find. Do you have that on yours? How do I get that. Note: mine is stock, I haven't installed any ROM on it.
