Basically jit CAN work on iOS but it is only enabled on apples own 1st party apps that come preinstalled on the device. If any 3rd party app tries to use jit then the OS will kill the app.

There is a jailbreak tweak called Nitrous and what Nitrous does is enable the Nitrous javascript engine that is used in safari to be used with other apps. Now you may be wondering what this has to do with ppsspp? Well basically the Nitrous javascript engine uses jit so im guessing that the Nitrous jailbreak tweak somehow gives permission for 3rd party applications to use jit without being killed by the OS.

I havent tried this out myself yet since nitrous is a paid tweak but if anybody is willing to try it out this could be a potential solution to getting jit to work on ppsspp without crashing.

I'm testing this approach now, but I don't think it will fix the problem. I don't think it works the way BubblegumBalloon describes it. I think it just substitutes Nitro for the regular JavaScript engine for 3rd party apps and doesn't universally enable JIT.

You guys here might still try contacting the developers (Joe Jordan) about it.

I'll update this post or post again once I complete my tests.

Seems like an awful lot of trouble to go to just to get an emulator to work on ONE platform . . .

I think the best approach is contact saurik or someone on the jailbreak team. They might be able to help design a tweak to enable JIT for PPSSPP . . .
