Apple denies iPhone tracking claim
Apple has dismissed reports that its iPhones store their users' locations.
It said reports last week that they could be used to track their owners' whereabouts arose from a misunderstanding of how the phones determine where they are.
The company said the data file uncovered by researchers and publicised is not a log of a phone's location, but a list of Wi-Fi hotspots and phone masts nearby. That helps the phone work out its location without having to listen for faint signals from GPS satellites.
Apple also said a software bug caused the phones to keep the data longer than intended.
It is the first comprehensive response to claims that iPhones store up to a year's worth of user location data.
