That is a good question. I too have wondered if there was an app when one accidentally delete a photo, video, or music song.
I know it's probably too late, but my preventative measure for something like this is to snyc all my pics/videos in dropbox. Worst case I only lose the photos I have taken since the last time I was connected to wifi
