The latest update to the Dropbox app for iOS enables users to share files to Facebook and Twitter. You can post pictures to the popular social services and attach files to Facebook messages.
The update also allows support for AirPrint, meaning you can now print Dropbox pictures or docs via Wi-Fi.
It’s a nice feature to have, especially now that iOS 6 is coming to the iPhone with complete Facebook integration besides the Twitter one.
Lastly the update adds support for Korean.
