how do I turn on Backup for my Iphone 5 on the icloud? My icloud storage of 5GB was full and i dont want to buy more. So i decided to clear all that was saved on icloud and I went to "manage storage" and selected my device and turned the back up off. Now i want to back up again because Ive deleted unnecessary things and there is no option for me to "turn back up on" under "manage storage" setting - please help, what must I do!!!? Thanks!
