This is some of my tracking data that Apple's IOS has been collecting and storing on my iPhone. The recent IOS 4.3.3 update reduces the scope to 7 days and doesn't copy it to the backup folder on the computer anymore but before I install this update I thought I'd take a look where I'd been recently.
I have shown you the UK data only statically, but you can display the day by day movements too. The full world map also tracks me visiting Brazil, Argentina, Uruguay, Northern Ireland, Holland and Germany. Scary.
