I'm not sure about the answer for that, but personally I'd recommend you don't do it if you can. Sony kept updating the PSVita for a while, cancelling out a lot of jailbreaks and I have a solid feeling they'll do the same for the PS4 for a while now. Hell, I wouldn't be surprised if they started attempting to brick jailbroken systems.
