Your iPhone and 3G iPad are tracking your every movement

Yesterday was a stellar day for Apple, with earnings that stunned Wall Street yet again. And yesterday was a bleak day for Apple, as it was revealed that iPhones and 3G iPads both have software that keeps a record of wherever you go. According to  flurry of articles, including the New York Times and The Guardian, two computer programmers found that a system update a year ago installed software that stores your location data, which it apparently gets from cellphone towers and Wi-Fi networks. Plus, when you sync your iOS device, that information is transferred to your desktop computer. The programmers who made this discovery have posted a free utility that lets you look at the logged information. That page also has a FAQ that answers questions about their discovery. This information apparently isn't being transmitted externally, and it's not yet known why Apple chose to log this information on your device.
