What's the best free iPhone recovery program for Windows?

I somehow managed to delete nearly 3,000 pictures off of my iPhone, went to the Genius Bar and was told that I had little hope of getting the images back. I decided to do some research myself and found programs such as Dr. Fone which was unable to recover anything. I stumbled upon a Tenorshare Data Recovery program, connected my phone, and thumbnails of all of my lost pictures were brought up. However, it wouldn't let me actually download the picture without paying a $60 membership type of deal. I'm a broke college student… Any other options?
