I have my girlfriends iphone 5 set up for icloud backup. She has zero pictures in her camera roll and has turned off all app data from being backed up. It says that we have 5.0gb of 5.0gb of icloud storage available. My problem is that iCloud is still telling us she needs 5.5gb for her next back up and wont back up the phone because she does not have enough storage space to complete the backup. I dont get it. Help?
