How to downgrade back to IOS 6.1.2?

I mistakenly updated my iPhone 4S to IOS 6.1.3. I am planing on using the evasi0n jailbreak but it currently does not support IOS 6.1.3. I know there is a way to go back to IOS 6.1.2 but I cannot recall it. It would help if you could provide me a link to the website or give me instructions.

Thanks

Added (1). If you also know of a jailbreak for IOS 6.1.3 that would be helpful too. :)

Do you have a ipod touch 4g, iphone 3gs or iphone 4 and saved your shsh blobs to downgrade? If you don't have those devices or dont have the blobs you cant downgrade, sorry =(

Sniper is right.

But even then that may not work. It's really difficult to roll back any iOS especially since iOS 4 (and now we're on 6). You really do need blobs, SSH, jailbreak, etc.

iOS 6.1.3 breaks jailbreak. And the jailbreak community is warning EVERYONE do not Update to 6.1.3 because there's no jailbreak for it atm.

I'm sorry but looks like you will have a non-jailbroken iPhone for quite awhile. Those are the facts.

There is no way to downgrade from IOS 6.1.3 for Iphone 4S nor 5. And evasi0n has no plans to jailbreak 6.1.3. You'll have to wait for the IOS 7 jailbreak. Sorry for the bad news…
