The iPhone location database has gotten mainstream attention, and I’ve had many of my less technical friends asking what it’s all about. Marco Arment wrote a post that is somewhat of a mini state-of-privacy address. For anyone concerned specifically about the iPhone location issue he writes:
Most of what your iPhone knows about you is stored on your iPhone — a device in your physical possession that you can quickly wipe locally or remotely at any time — and, as far as we know, is not transmitted to Apple or anyone else. To access your private data, a snoop or government would need physical access to your phone.
