Foursquare announced version 2.0 of its iPhone app, as well as a new way to connect it to the web. There are three main features that Foursquare is emphasizing with today's announcement. The first feature is the splitting up of tips and to-dos. "Our thinking is that by making it easier to access your To-Do list, foursquare will be better at helping you remember all the interesting things you want to experience nearby," says the Foursquare team .
