Confirmed: Your iPhone Is Tracking Your Every Move

…and an explanation of how it works:

To test this, I plugged in my iPhone and fired up iTunes… I then had to run a manual backup to make sure the most up-to-date tracking data had been downloaded to my Mac from my iPhone.  To force a manual backup, right-click on your device in iTunes on your Mac and choose Back Up from the menu:
