Is there a reliable jailbreak for iOS 6?

I have iphone 4S with iOS 5.1.1 and want to update software to v. 6 iOS, is there a reliable jailbreak for the latest software?

There's a tether jailbreak, but that's it. You are fine in 5.1.1 if you are jailbroken.

Unfortunately there's no untethered jailbreak for iOS devices with iOS 6 yet.
You can just do a tethered jailbreak for iPad 1, iPhone 3GS, iPhone 4 and iPod touch (4th Genearation) with iOS 6.

As of right now, the dev teams are in the process of coming out with a jailbreak for all devices running ios 6. The only ones that can be jailbroken are itouch 3G itouch 4, iphone 3GS iphone 4.very soon though the jailbreak should be released so until then just hang in there!
