How to upgrade iphone 4s to 5.1.1?

Just as the title said, is there a way to? I want to jailbreak my iphone 4s which is on ios 5.1, but there haven't been any jailbreak for that in recent months. So i'm thinking of upgrading it to 5.1.1 but i'm afraid that it might erase my stuff after updating. Can anyone help?

You can't update to a specific firmware. You can only update to the latest firmware which is iOS 6. There are no jailbreaks available yet for iOS 6 so you're going to have to wait. Sorry!

Backup everything first. I learned the hard way.
