Dropbox for iOS was updated to version 3.0 a few days ago, adding a complete iOS 7-style redesign. The app features a revamped App Store icon and an overall design that incorporates more white space, a cleaner look, and lighter, less obtrusive navigation bars. Folder and menu icons have also been revamped.
In addition to a new look, the updated version of Dropbox features a streamlined iPad experience plus improved sharing and exporting. It also incorporates AirDrop support, speed improvements, PDF viewing updates, and bug fixes.
