Your iPhone or 3G-equipped iPad has been secretly recording your location for the past 10 months.

Wired.com can confirm that fact: The screengrab above shows a map containing drop pins of everywhere yours truly has been in the past year.

Software hackers Peter Warden and Alasdair Allen discovered an unencrypted file inside Apple’s iOS 4 software, storing a long list of locations accompanied with time stamps. The file is labeled “consolidated.db.”

“Ever since iOS 4 arrived, your device has been storing a long list of locations and time stamps,” Warden and Allen wrote. “We’re not sure why Apple is gathering this data, but it’s clearly intentional, as the database is being restored across backups, and even device migrations.”

Warden is providing an open source program “iPhone Tracker” for iPhone and 3G iPad customers to output their location file into an interactive map, like the one above, so they can see for themselves. All you have to do is plug in your iDevice through USB and run Warden’s application. The software requires OS X 10.6 (Snow Leopard).
