Android phones, apps and tablets

This http://en.wikipedia.org/wiki/Telecommunications_data_retention#United_Kingdom says that they keep most data for 12 months under a voluntary agreement with the Home Office.

However the pertinent bit (that I mentioned above) isn't covered by that code, which is:

• The capability to determine the location of a mobile telephone to within a few yards by using triangulation and multiple base stations.
  
  

Only the police and security services get that... so I suspect the telco would respond by saying that it's used for crime prevention and therefore exempt.
