I am not sure how many have heard about or actually even care.
But, this does sound scary as sh*t to me! It’s time that we as consumers have more choice on what information we choose to ‘share’ with providers and vendors. Things like this should be disclosed to consumers.
“Security researchers have discovered that Apple’s iPhone keeps track of where you go – and saves every detail of it to a secret file on the device which is then copied to the owner’s computer when the two are synchronized.
The file contains the latitude and longitude of the phone’s recorded coordinates along with a timestamp, meaning that anyone who stole the phone or the computer could discover details about the owner’s movements using a simple program.
For some phones, there could be almost a year’s worth of data stored, as the recording of data seems to have started with Apple’s iOS 4 update to the phone’s operating system, released in June 2010.” [from here]
So if someone were to get a hold of either your phone or gain access to your computer they could find out where you go often, what time and how often.
