i did a backup using iCloud and reached the max 5 gig.
now..i erased the old backup and i saw at the Settings that i have now have 5 gig total to backup and 5 gig available.
when i am trying to backup my iPhone using the iCloud, i am getting the alert "NOT ENOUGH STARAGE, this iphone cannot be backedup because there is not enough icloud storage available. you can manage your storage in settings"
i am going to settings and i see that i have no backups and that i have 5 gig free inorder to do the backup!!
