So I've been reading regarding iCloud and it seems like you can't use iCloud as a back up? Basically, my iPhone is full of photos. I want to free some space on the iPhone by transferring the photos to iCloud. Once they're all in iCloud, I'll delete said photos from my iPhone and free up some storage. After reading many threads and discussions that people have online, seems like you can't do that. If you delete the photo from you iPhone, you're also deleting the copy that you saved on iCloud. If that is the case, after I sync my photo to iCloud, I'll turn off the photo sharing with iCloud and then delete the synced photo from the iDevice, therefore, keeping safely keeping the photos on iCloud. But if turn it back on, will it erase the previous photo from iCloud?
