Similar to the major facelift that the Facebook App got a couple months back, LinkedIn has given its business networking application an overhaul that LinkedIn/iPhone users have been dying for! After playing around with the app for a bit, I'd say that this is a game-changer for LinkedIn -- bringing functionality to not only the app, but to the entire network and service. It's a slick interface, with smooth functionality and the ability to browse and connect with your network. The biggest new feature is the "In Person" button, which allows you to link up and exchange "digital business cards" over bluetooth! This is a major time saver -- now I won't have to spend hours entering all that contact info in my address book and then searching for them on LinkedIn. If only they could make the main site as sexy as this app, it may well prove its worth!
