My iPhone 4 is constantly running out of storage space. I do have about 50% of my storage allocated to music, but I'm not sure how to make room in the other 50%. My apps don't take up that much space and I don't have that many photos on my phone. However, my photos show up both in my Camera Roll and in my Photo Stream. I thought my Photo Stream was for iCloud backup, but when I go into my settings it says I have 5.0 of 5.0 GB available in the iCloud. Could my phone just be backing up the photos onto the phone itself instead of the cloud? And does anyone know how to fix this? Thanks!
