Connect to Dropbox
Dropbox hasn't released an official app for BlackBerry 10, but the free, native Connect to Dropbox app, from BlackBerry, is the next best thing. The software brings all the basic cloud-storage functionality to BlackBerry 10. Access all your Dropbox files; view, edit, and add files to Dropbox; browse files in the cloud using the BlackBerry 10 File Manager; export files to other apps; and save new and updated files to Dropbox. I'm anxiously awaiting an official Dropbox app that doesn't need to use the BlackBerry File Manager, but until then, I'm calling Connect to Dropbox a friend.
