Vulkan

or it was stolen so you lock the phone using iCloud wouldn’t this allow a really intelligent thief to run or modify code that bypasses the iCloud lock? Now I’m not talking about secure data because that could be wiped for all they care. If this allows for the eventuality of a jailbreak and the ability to run tethered code it could potentially allow useless phones to become useful and increase thefts provided the phones don’t become blacklisted. I’m not sure if after you bypass the iCloud lock it becomes permanent or not once your outside of the setup screen, but if a jailbreak comes along that allows for semi-tether this could give it persistence.

What I’m saying is their is still some out of the box risk scenarios. 

No. There's more about why this is the case in the interview with the developer. 

And, the possibility of theft of an iPad is unchanged with or without the jailbreak. so the threat profile remains the same before and after the reveal of it.
