And with one small settings change the three dot menu bar is gone
Info for rooters:
the 4.2.2 update also updates your bootloader. You'll still be able to use the HTCDev unlock (I expect), but you will not be able to use revone to gain S-Off, and probably not moonshine either (not confirmed - the XDA thread for that is very quiet).
This may change in future, but right now if you are interested in S-Off do it before accepting this update, as you won't be able to after.
(Further discussion of this should be taken to All Things Root).
