Dropbox BlackBerry Z10 - You simply login to your DropBox account using the “Connect to DropBox” app. After that you have an easy option to choose if you want it to sync over cellular connections. Personally I do not see the point because the DropBox client works better on BlackBerry 10 than it does on iOS and Android. It provides seamless access to your DropBox account from the file manager. That means that ANY app can access DropBox and perform actions or save data there.
