Dropbox for iOS adds folder notifications and new PDF viewer

The Dropbox iOS app has been updated to make managing cloud data and documents easier on an iPhone or iPad. Dropbox has a new PDF viewer that improves the way documents are displayed, and an option to sort files according to the date that they were modified rather than sorting by name. Users can access the feature by tapping the button left of the search bar and selecting "Newest - Oldest." Dropbox also added push notifications to alert members when someone has shared a new folder with them.
