I located the folder with my backup from right before I upgraded. All the photos that were in my Camera Roll on the phone are there. They all have names like 'b6125080e908b6a84c6ed7c516fd8b53281c9f72'. But a 'restore' operation doesn't bring them back. I have no photo folders on the phone. I can, however, go into iTunes and enable 'Synch Photos from' and give it a folder with some other images in it. Those show up on the phone in a new folder (same name as the folder I chose in iTunes). AND I get a Camera Roll folder -- but it is empty. For some reason, it steadfastly refuses to restore the previous photos from my backup. Being new to the iPhone by only a few months, and this the first upgrade ever for me, I'm at a complete loss for how to fix this. I'm not entirely sure whether it may be a bug/limitation/'known problem'/'normal behavior' with IOS 5. Anyone able to enlighten this unenlightened person?
