So I have lots of pictures on my camera roll. Is there a way to sort them into different folders on the phone? Or do I have to somehow do that on a computer?
You can do it with iTunes. Sync your iPhone in iTunes so that all the pics from Camera Roll get put into iTunes. Then sort the photos within iTunes into the different folders that you want, and sync those folders to your iPhone.
