Only two short weeks after executives from Apple, Google, and other tech giants provided testimony on Capitol Hill regarding mobile security and privacy concerns, questions and lingering apprehensions about these issues haven’t subsided in the least. Well aware of the persistent concerns, one prominent US Senator has formally reached out to Apple and others, saying the time has finally come to either put up or shut up.

On Wednesday, Senator Al Franken (D-Minn) sent a letter to Apple and Google that calls for the creation of mandatory privacy policies from all apps offered via Apple’s App Store and Google’s Android Market. It was Franken’s judiciary subcommittee hearing on mobile tech privacy that initially enabled Apple and others to be grilled in such a high profile matter on these issues.
