Foursquare may be the next Twitter. This location based social networking application, was initially rejected by Apple but after a second submission by its founder, Dennis Crowley, it is now available for your iPhone.
It comes with an innovative design which allows users to interact with friends while discovering their city. You get points and badges for special achievements by checking in with the application wherever you go which includes: restaurants, bars and nightclubs. For now the database only extends to the U.S. and the 12 larger metropolitan areas like Chicago, Portland, Seattle, Austin, Boston, New York, San Francisco and LA.
So while you do your usual friday night drinks with the boys/girls this cool application rewards you for it!
Who has it and what city are you in?
