With the Social app, you can let your friends know where you are, so they can find you.
Select > Social.
Select the text input field at the top of the view.
Add your location. The phone uses GPS to determine your current location, and searches for landmarks near you.
If several landmarks are found, select one from the list.
Location sharing is available only if it is supported by the service.
Before sharing your location, always consider carefully with whom you are sharing. Check the privacy settings of the social networking service you are using, as you might share your location with a large group of people.
