I recently broke the screen on my Tour and got a new phone. I was able to transfer everything from my old phone onto my computer and then onto my new one except for my pictures. I cannot find them when I have my old phone plugged into my computer.
I always make sure to save my pics on the Micro-SD card. That way I can
plug it into a micro-sd USB reader if anything happens to my Tour and recover them all from there.
Not sure how you are going to get them back if they are stored in Device memory.
