> If you're privacy conscious, why do you have a smart phone at all? Get a standalone GPS There are trade offs between privacy and security, it's not an all or nothing affair. Even a dumb phone can be tracked via cell tower pings... I think most people who say things like you did aren't effectively thread modeling. For example, while I do own a smartphone, I turn it off and put it in a faraday bag during Defcon :) >Even in airplane mode, your phone is tracking where you go with the accelerometer. I don't have time to look up the video right now, but this has been tested. I'll acknowledge that's theoretically possible, but I'm selective about what apps I grant location privlidges to - I don't think most companies would want to risk fines etc by circumventing. If I'm attending an especially sensitive meeting, I wouldn't bring any phone with me.
