I am using an older iOS device with 64 Gb storing capacity as "main storage" for pictures, by using iCloud to automatically sync pictures from my new 8Gb device. Since my new device has limited storage capacity I would like to be able to delete pictures from this new device (e.g. when travelling), knowing that the pics are kept safe on my 64 Gb device. Is it possible to prevent pictures uploaded to one iOS device from being deleted when deleting it on another device? (... hope this explanation was possible to understand ...). With or without jailbreaking?
