That data is easily available via tower pings without needing to unlock the phone. Who sets up their phone to record constant GPS coordinates?

apple, iphone saves timestamped gps coordinates every time it discovers available wifi network

  Which iOS? Link available?

    are you living under a rock for the last 10 years? here, first google result for the "ios location data": http://bgr.com/2015/04/01/iphone-location-tracking-map/ http://bgr.com/2015/04/01/iphone-location-tracking-map/

      I was expecting you to link a 10 yr old article to prove your point.

      Where does this show that "the iPhone tracks my location every time it discovers a wifi network"? Sure I can have given permission for tracking to an app but if I haven't where does the iPhone/iOS store my location data? ps: downvotes?

Tower pings aren't terribly accurate.

Do towers record past telemetry data? Assuming they do, the granularity of knowing that a particular tower handled a phone ping is comparatively useless. A guessed location (stored on the iPhone) based off of cell tower triangulation and the occasional GPS calculation is far more valuable. I do agree that we should consider the FBI's statement with skepticism.

No, it's not. A simple correlation with other phones tells you who is traveling together (co-travelers). This only requires knowing which phones are near each tower, at a fairly low temporal granularity. I'm sure there are additional ways to analyze that data, too. The travel and relationship map that COTRAVELER discovers is merely the project we know about.
