Dropbox had been one of the biggest apps yet to receive a refresh in line with Apple's radical iOS 7 visual style, but that changes today. First teased earlier in the month when Dropbox announced a host of features focused on business, version 3.0 brings a cleaner design, new blue-on-white icon, and improved iPad interface that lets you easily switch in and out of fullscreen mode with a single tap. The app also supports iOS 7 features such as AirDrop, and Dropbox promises major speed improvements for viewing photos and playing back video. It's available now in the App Store.
