After it was learned that one can access data stored on iPhones, iPads, etc. and determine the locations the device has been, privacy concerns were raised. Senator Al Franken (D. Minn.) wrote to Steve Jobs and asked for an explanation. Concern was raised about secretly recording and compiling customer location information.
Today, Apple has responded. Apple asks and answers questions about the issue. Further, Apple states that it will be releasing a free iOS software update that will reduce the size of the crowd-sourced Wi-Fi hotspot and cell tower database cached on the iPhone, cease backing up this cache, and delete this cache entirely when Location Services is turned off. Further, the next major iOS software release will encrypt the cache storing the data.
