Facebook has launched a new feature called places which allows you to share geographic location as your facebook update on your facebook timeline with your friends. It could be a case when you find a place you really like, you want to tell your friends you’re there. Maybe it’s a new restaurant, a beautiful hiking trail or an amazing live show.
You have the option to share your location by "checking in" to that place and letting friends know where you are. You can easily see if any of your friends have also chosen to check in nearby. You can easily do it through iPhone application or touch.facebook.com site and then tap the "Check In" button. You’ll see a list of places near you. Choose the place that matches where you are. If it’s not on the list, search for it or add it. After checking in, your check-in will create a story in your friends’ News Feeds and show up in the Recent Activity section on the page for that place.
When you check in, you can also tag friends who are with you, just as you can tag a friend in a status update or photo. You can post an update along with your check-in to tell people more about what you are doing. With Places, you are in control of what you share and the people you share with. You choose whether or not to share your location when you check in at a place. When you check in, you can tag friends who are with you but only if their settings allow it. When you are tagged, you are always notified.
When a friend tags you through Places, you will receive a notification on Facebook and on your mobile device. The first time this happens, you’ll be given the choice to allow your friends to check you in to places. You can always remove any Places check-in or tag using your mobile device or on the web. It’s like removing yourself from a photo tag. You also have the choice to turn off the ability for friends to check you in at Places. Go to your Privacy Settings and turn off the setting to "Let Friends Check Me In"
Please note – You can do this from any mobile phone browser not only with iphone but also on other mobile phone browsers by opening touch.facebook.com provided if your mobile browser supports HTML 5 and geolocation feature.
