Not finding it all that useful. Doesn't seem to be any folder support for the folders in your BlackBerry/Pictures folder. This only allows me to upload from the root. Lost of issues seeing the icons of photos in the root as well.
Then, anything I have in the photos folder of DropBox can not be saved to the BlackBerry. It just allows viewing.
