This is - at best - a temporary solution.
Seems the key is being able to unsolder a chip ... I am sure it's not beyond the wit of man to circumvent this.
In fact I would expect such circumvention to feature in the next iPhone iteration - it's more useful and exciting than the lack of a headphone jack.
Off the top of my head:
1) Physical protection - any attempt to unsolder the chip destroys it
2) Device key encryption - the *correct* NAND array contains a key which generates the rigth reponse to a challenge. Something an impostor can't.
3) Some small explosive devices with acid which trigger when the case is opened.
(I may have made that last one up ...)
Biting the hand that feeds IT
