Apple's iPhone 4 Tracks Where It's Been

NPR's Martin Kaste reports.
MARTIN KASTE: Alasdair Allan says the iPhone 4 is constantly recording its location relative to nearby cell phone towers and Wi-Fi signals. He found the data when he was looking at the files created when you sync your phone with your computer.
ALASDAIR ALLAN: I stumbled across a directory that's actually named Location D, and I thought well, that looks interesting - which was full of latitudes and longitudes and time stamps.
KASTE: Allan and Warden say the iPhone tracking was already a known piece of inside knowledge among hacker-types, but they wanted to make sure everybody was aware of it. Warden says there's no evidence the location information is being sent to anybody else.
PETE WARDEN: So don't panic, but we do want to know more about what's happening with this data.
