How to recover a deleted video off camera roll on iPhone 4s?

I recently recorded a video on my iPhone, but before I connected it to iTunes I accidentally deleted it. It is vital that I get it back but after extensive google searching, I can't find any program that can recover lost files for iPhone. Any help on what program I could use would be greatly appreciated!
