Dropbox for iOS has been steadily improving since it was released, but the latest update makes the service easier to use on both your phone and your computer, along with introducing new file management options.
The biggest, or maybe the most interesting, development is the ability to set up Dropbox on your computer using your webcam and iPhone. In the updated app there is a section called Connect. After you click Connect, the app prompts you to visit http://www.dropbox.com/connect, and point your iPhone at your webcam, which scans a QR code that downloads Dropbox to your computer and sets up your account for you. If you've ever struggled to explain setting up Dropbox to a computer-illiterate friend, this change will make your life easier.
File management also gets a big boost. The app has added recently used locations to make saving files to your most common folders easier. In addition to recent locations, Dropbox has streamlined favoriting files to ensure the files you need are always with you.
Now users can move files around in the favorites tab by simply holding on the file and dragging. In addition, by swiping right on a file in your favorites the app now saves the file to your phone so it can be accessed even when you're offline.
Finally, the app has added support for four additional languages: Danish, Dutch, Swedish, and Thai. You can find the latest version of Dropbox right now for free in the iTunes Store.
