Okay, this is creepy:
In a 13-page reply to questions posed by Representative Ed Markey from Massachusetts and Congressman Joe Barton from Texas, Apple said it collects GPS data daily from iPhones running OS 3.2 or iOS 4. The phones collect the GPS data and encrypt it before sending it back to Apple every 12 hours via Wi-Fi. Attached to the GPS data is a random identification number generated by the phone every 24 hours. The information is not associated with a particular customer, Apple said.
Apple uses the data to analyze traffic patterns and density, it said. Apple collects such data from customers who have approved the use of location-based capabilities on the phone and who actually use an application that requires GPS.
It’s all in the click-through license, Apple says, adding that if you don’t want your phone to report your location, all you have to do is disable the GPS on your phone. Sheesh.
It’s not been a good week for Apple.
