Q: my device is not listed in manage storage on iphone4s so I can't manage it

Just to be clear, when you go to:

Settings > General > Storage & iCloud Usage

there are normally two types of storage listed,  1) STORAGE for the physical storage on your phone and 2) ICLOUD for the storage your iCloud account is using.  If you "deleted iCloud" then all you have left is the physical storage on your phone.  Tap "Manage Storage" under STORAGE and it will show you the storage your phone is using & available and how much each app is using.

This might help you understand it a little better.

About storage on your device and in iCloud - Apple Support

You may see that the figures don't add up to what the message is stating. You might add up all of the storage on the device and think that you should have more space available. It could be that your space is being taken up by "other" data on your phone. You can not see this on the device itself, you can only see it when connected to iTunes on your computer.
