Any implementation details? How will the autodestruct signal be sent? And if the consumer can opt out of the kill swtich, wouldn't the thief also be able to opt out? I have a bad feeling that 10 years from now you will have to wipe your phone and install some makeshift build from xda right after purchase just to use it confidently.
