Guys, you're reading this wrong …
This does not mean that you're at more risk if your phone is jailbroken.
It also does not mean that you're safe if your phone isn't jailbroken.
It means that as long as jailbreaks are possible (i.e. Apple hasn't fixed all the holes), targeted attacks like this are also possible. Even if your phone isn't jailbroken, they can just come do that while you're in the shower. Someone willing to pay 50.000€ for the exploit would certainly be willing to break into your house, after all. But chances are, your secrets aren't worth that much, so you can relax.
Better worry about mass surveillance and communicate with encryption only. That's how your privacy is actually being invaded. And that's the part you can easily fix.
