Do NOT update directly from the settings,that bricks Jailbroken devices.
The only way to update safely is through iTunes on a computer.

Well you'd have to restore your iPhone 4S (through iTunes) then update it to the latest ios (which is currently ios 7.12).

You will need to back up your iPhone (well, you do not need to), then restore from backup once you restore completely your iPhone to iOS 7.1.2.
