But I want to delete photos from my Camera Roll on my Iphone. Using ICloud won't delete photos from my Iphone.

I have imported all my photos to my IMAC. I have backed everything up on Iphoto and Itunes, but cannot delete my photos from my camera roll unless I do each one separately. Since I have nearly 4,000 photos, that will take forever. I don't want to lose photos from my Ipad through ICloud either.

I would love to know how to do this because I need space on my phone for more photos. Thank you.
