An anonymous reader writes with a report from Spiegel Online that the U.S. government "has the capability of tapping user data from the iPhone, [and] devices using Android as well as BlackBerry, a system previously believed to be highly secure.
The United States' National Security Agency intelligence-gathering operation is capable of accessing user data from smart phones from all leading manufacturers. ... The documents state that it is possible for the NSA to tap most sensitive data held on these smart phones, including contact lists, SMS traffic, notes and location information about where a user has been."
As a bonus, the same reader points out a Washington Post report according to which "The Obama administration secretly won permission from a surveillance court in 2011 to reverse restrictions on the National Security Agency's use of intercepted phone calls and e-mails, permitting the agency to search deliberately for Americans' communications in its massive databases ... In addition, the court extended the length of time that the NSA is allowed to retain intercepted U.S. communications from five years to six years — and more under special circumstances, according to the documents, which include a recently released 2011 opinion by U.S. District Judge John D. Bates, then chief judge of the Foreign Intelligence Surveillance Court."
