Your phone's location can be silently triangulated based on what cellphone towers can see your phone and the strength of the signal to them. This is being done and you can buy the data from LocationSmart. This was discussed on HN a few weeks ago [0]. This data was used in Italy to catch CIA agents after they extrajudicially extradited (so to speak) a terrorist[1] in 2003 https://youtu.be/BwGsr3SzCZc?t=7m2s https://youtu.be/BwGsr3SzCZc?t=7m2s. The whole talk is worth watching. The cost of storing this forever is negligible and going down. The government would be foolish or (in my opinion irrationally) principled not to hold on to this for the next 1,000 years.
