That iOS devices like the iPhone are permanently storing location data has been all over the press last week. See for example the story on wired.com or on CNN.

This video demonstrates how our tool AlpAlyzer (named after the iPhone default password "alpine") helps in locating and visualizing this data.

The tool itself has not been released yet, since we need to test it on more devices. Anyone willing to contribute their location data file for further research please contact us.

While it's not nice to find out your movement has been tracked on your device, it's not like this data was shared or even sent to Apple. Without the danger of this data being "stolen" by jailbroken apps or software on the desktop, it could be neglected. The spying done by most iPhone apps (those using tracking modules) is more disturbing really! Spybot-S&D 1.6.2 can already detect such apps on your iPhone. So download and install it if you haven't already.
