If you have location services enabled on your iPhone, you can see a map of all the places where you're iPhone has tracked your location. In addition to viewing a map, you can also see a list of all the places you've been.
The feature is easy to turn off, too, if the idea of your iPhone logging each place you visit bothers you.
Here's how to see the map:
Tap the "Settings" icon on your home screen.
Tap "Location Services."
Scroll down to the bottom of the menu and choose "System Services."
Then scroll down and tap "Frequent Locations."
Now you'll see a list of the different cities you've been to in the "History" section.
Tap one of the cities to view a map of all the individual locations you've been to in that city.
If you want to erase these locations, press the "Back" button in the upper right corner of the screen and choose "Clear History."And, if you wnt to turn off the feature in general, press the switch next to "Frequent Locations" on this screen.
