Gowalla is an amazing new and social way to record your memories, keep up with your friends, share your favorite places and discover the the world around you. Now, Gowalla has integrated FourSquare, Facebook and its own check-in network, plus a bit of Twitter, into its own app. One check-in on Gowalla 3.0 iPhone app allows you to syndicate that check-in across all four major location-aware networks.
Gowalla app will also pull your friends' location-based activities from other networks directly into the app, meaning you won't have to jump between services to see where each of your friends are and what they're up to. Gowalla has even done the leg work to sync up venue locations between the competing services, meaning that one gig check-in will correctly tag you at the concert venue across all services, and then later, at the bar down the street for the after party.
It has several other updates including the ability to leave notes for a friend at a location, browsable city highlights, bookmarkable places, and ability to flag problems at a location such as a closed down pub, or a shop undergoing renovation.
