I agree this is "a step in the right direction", but if the iPhones are special, would the exploit run on them?

I suppose it depends on how "special" they are—do they run standard iOS with normal Safari and actual apps?

I think it just means they can run unsigned code. But yes, I would presume that Safari and the other default apps are present.

Production iPhones can do that already. Three phones probably give researchers root access and allow for disabling AMFI, etc.
