I have lost my restore backup when I downgrade from 1.1.3 to 1.1.1 before..
I still have all the photo backup in iPhoto, but I could no longer put them back to the camera roll since I dont have the .thm for each photo..

Does anyone know any program that can do that? I know the Wallpaper app can save the wallpaper to camera roll, but I cant browse my own photo with it.. Is there a program similar to that so I can put back my backup to camera roll??
