How to degrade from iOS 6 to iOS 5 in iPhone 4S?

Only if you saved your SHSH Blobs

Who in their right mind would want to? And you can try restoring your iPhone but don't think it will help becasue it auto-downloads the most current iOS

Have you previously jailbroken your iPhone while it was on iOS 5?

If yes, then look here: http://www.redmondpie.com/downgrade-5.1-to-5.0.1-5.0-4.3.3-4.3.5-on-iphone-ipad-ipod-touch-how-to-tutorial/
(I know it says iOS 5, but the procedure is basically the same)

If no, you're S. O.L.
