How to unjailbreak my iPhone 4S? - 1

I'm in a rural area and I didn't bring my laptop with me. I know two ways to backup my files. First one is to backup with iTune and the second way is to use iCloud. I can't do the first solution because I don't have a laptop.So… How do I unjailbreak my iPhone using the second option? I can't find where to restore my iPhone in the phone setting.

The only way to Unjailbreak an iPhone or any iDevice is by completely restoring the software. If you have any Wi-Fi network nearby, connect to it and the iCloud backup runs automatically.
