Foursquare have given their iOS app an update, pushing it up to version 6.0. The latest release sees the Explore part of the check-in app stretch its legs, where it now has the Explore search box on top of the navigation bar - completely replacing the Foursquare logo.
There's an updated auto-complete engine that helps provide users results faster than previous versions, and the friends list is no longer a list of friends, but is a very hefty chunk of recommendations mixed with trending places, and people that you know that are nearby. Less-used features of Foursquare that resided in the "Me" tab are now in a drawer that slides out from the app's left side.
Foursquare 6.0 for iPhone also cuts down the functionality of the main screen, giving the cut parts to providing space for trending places and recommendations instead. When you open Foursquare 6.0 on the iPhone, it will respond to the date, time and location in a very different way. If you were to visit a particular restaurant, Foursquare will tell you where people usually go after visiting that restaurant, such as a local bar.
