NSA slide from May 2010 meeting, via New York Times.
From a New York Times report today, based on the contents of NSA documents leaked by Edward Snowden:
The N.S.A. and Britain's Government Communications Headquarters were working together on how to collect and store data from dozens of smartphone apps by 2007, according to the documents, provided by Edward J. Snowden, the former N.S.A. contractor. Since then, the agencies have traded recipes for grabbing location and planning data when a target uses Google Maps, and for vacuuming up address books, buddy lists, phone logs and the geographic data embedded in photos when someone sends a post to the mobile versions of Facebook, Flickr, LinkedIn, Twitter and other services.
