What about LOTS of phones? First I just thought about it being harder to track and hack someone who isolated activity & data across multiple phones, but what if instead of or on top of that practice you were able to constantly throw them away like in a Hollywood spy movie. They don't have to be disposable though. We just need some sort of tamper-resistant/tamper evident phone and then a service that ships you a random phone every week or month. Wipe and put the old phone in the return box - i[ncognito]Phone /spitball
