Foursquare, one of the world’s most popular social check-in services has just launched a significant update to their iPhone app- photos and comments. The feature that’s been requested by many users, has now been implemented, turning the service into a Facebook of some sort. Now in addition to checking in and leaving tips in locations, you can post photos as well. You can also comment on your friends’ check-ins, and they can do the same to yours. The update will be arriving for Android later this week, and BlackBerry users will get it in January. No word about the Symbian update though. Head over to the iTunes App Store to get the latest version of Foursquare now.
