Even though I think I'm out of luck, I'm hoping someone can help me. I used the camera to take a picture and decided I wanted to delete it. I opened the gallery, and the picture I took was on top of all the other pictures I've taken with my phone. I held down on it too long to open and it checked the picture to delete. Not thinking, I went ahead and clicked okay, but of course it deleted every picture I've ever taken with my phone. 
I do have Astro file manager, and I had all of my pictures saved to my SD card. Is there any hope at all of locating these deleted pics?
