The Dropbox application for iOS is getting more social after an update. The app now has options to be able to share content to Twitter and Facebook and will now also support AirPrint. Before the sharing options were very limited, to just email and copy to clipboard but now with this update you can post to Twitter or Facebook without a problem. This new update is only available at the moment on the iOS platform but should be coming to Android shortly. The AirPrint is also a very nice feature. So the app is available now on the app store and if you already have dropbox make sure to look for an update.
