"The choice to go with 3.1 was because of a limitation with 3.0.1. Under 3.0.1 if you record video from within the Dropbox app that video couldn't be saved to your iPhone photos directory, so if your upload was interrupted for any reason the video would be lost. With 3.1 we can save the video to your photos on the phone, so if the upload fails you still have a copy and can attempt to upload again.
