Facebook announcement showing a Modded HTC One X

So I was looking at the announcement page for Facebook's new layout and noticed something interesting.


Lets look a bit closer:


That is not Sense. It looks like the folks over at Facebook are running stock Android on an HTC One X. What I find interesting about this is the OneX has a locked bootloader and has to be unlocked through other non-supported channels. It is odd that Facebook would show this in such a public announcement. Or perhaps I have just been modding my phone too much lately...
