Most (if not every) recent (ie. pretty much anything I ever released, since the 2.5 era) jailbreaks & non intrusive hacks let official updates pass through unhampered.
(In fact, that was pretty much part of the whole point of the thing, be less intrusive, and thus easily removable).
What said new official updates then might do to the hacks already installed is another thing

. I can't say for certain that it won't break/disable this or that until I can put my hands on an updated device, and my K3 is currently still happily running FW 3.1
