I have that on my iphone, it has to be enabled. After 10 failed attempts to enter the password it will erase all personal data, it's also my understanding that it will limit the time between attempts past a certain number.
But again, Cook said he would take the phone to Apple labs and extract the info. Apparently that's not good enough?
I wasn't aware he had said that. I'm sure there would have to be some government people there watching the operation and monitoring what went on. Seems like a fair compromise though.
