How to jailbreak iPhone 4S 6.1.3? - 2

I heard of ifaith but I don't know much on it. Downgrading would help to if you can. Everything free please.

Google for "download IOS 6.0 ipsw" some sites like idownloadblog.com and redmondpie.com are good resources to look for. Anyways download that firmwre file to your PC.
Now go to www.redsn0w.com (it's a zero in redsn0w) and download the newest version of Redsn0w - save it in the same folder as your ipsw file you downloaded. ***Side note if you downloaded it from a site and it says it's a zip file and not an ipsw file you have to change the extension, right click on it and select "Rename" then all the way at the end change.zip to.ipsw and that's it).
Now open Redsn0w and click the More button, then click on Select IPSW - guess what… Browse to the ipsw you just downloaded and possibly renamed, it will ask if you're on old boot rom, just say no. Even if you think you are just say you're not.
Now click on the back button and finally click on Jailbreak - follow the onscreen instructions and in a few minutes you're gonna be all JB'd and ready to rock Cydia. Don't go to far from your computer though because you'll need to learn the beauty of a semi tethrered jailbreak. Every time your device gets turned off you'll have to connect to your PC and open Redsn0w, click the More button and then click the Just Boot button. You'll learn the fine art of entering DFU mode well too!
