I think jailbreaking is pretty done-with to be honest, which is a shame. I heard that 9.3.2 totally switched up the kernel. That could be a good thing (revealed new exploits) or most likely, really bad (closed pretty much everything up)
But yeah, hardly anybody is even working towards making a jailbreak anymore. We've got two Chinese teams (Pangu and TaiG(?)) and nobody else really even bothers (to my knowledge) I think the profit return is just too little now considering the work that goes into it, must be damn-near impossible to find any exploits now...
Could be totally wrong though. People have been saying "JAILBRAKING IS DONNEE FOORRR!!111!1!1!!!!1" since iOS 6 and its really long amount of time that took to get jailbroken, but we have had a jailbroken iOS 6, 7, 8, and now 9 (With a big delay after first release) so who knows. I almost got into jailbreaking for the first time with iOS 9 but quickly lost hope, and I have decided I don't want to get involved with the nightmare of waiting for new jailbreaks ALL THE TIME or else my phone will never be updated. I don't want to become dependent on a jailbreak in other words if it's such an unreliably released.
