Part One: Two, Three, Foursquare
Foursquare is an application that takes full use of your phone’s global positioning system (GPS). After you load the free application (and submit some quick profile information) your phone will tell you what’s around you: restaurants, bars, retail stores, hotels, sites, and various points of interest (to say the least). You will find friends that are also using the system by tying your Facebook and Twitter account to the Foursquare application. You then begin your journey with Foursquare by “checking in” to locations, which updates your status with a map icon and a pin, which is a nice touch.
