I currently have a 16 GB iPhone 5, with about 1.2 GB available storage. It's still on iOS 6 (I know, right?!) and I figured it's about time to update. Under software update, it says iOS 8.4 is 1.2 GB.
Does that mean the entire update will need just that much space, or will I need more than that considering I don't have iOS 7 and that it's a big jump from the iOS 6 interface to the iOS 8?
