Apple has been releasing iOS updates left and right lately, greeting iPhone owners with a prompt every time they start up iTunes. Many are wondering if these updates are important, what the purpose of the updates are, and whether or not it's actually worth the time to continue installing. When it comes to the latest update, iOS 4.3.3, Apple has made significant changes to the way in which location data is stored on your device.
Responding to criticism and questions from across the board, Apple is reacting to a discovery by security researchers Alasdair Allan and Pete Warden. The pair discovered a log file on the iPhone and iPad that keeps location data from cellular tower triangulation indefinitely. With software they wrote, they were able to see maps of where they had been with their iPhones ever since the iOS 4.0 update was installed.
