I think I am right about this, but just want to be 100% sure before I buy into drop box storage vs icloud storage. There is no such thing as true photo backups on icloud right? I know it can keep 1000 photos in your photos stream or photo's currently in your camera roll (meaning you would need to keep the photos always on your phone). In other words, there is no way to pay for icloud storage and have it work like dropbox. I cannot remove the photos from my camera roll and just leave them "in the cloud." I know I can unload the photos to a separate hard drive, but I want a cloud storage that can actually store my photos without having to leave them in my camera roll. Is that correct, or did I miss something? TIA.
