Via iPhone in Canada is the How to Jailbreak iOS 6.1 with evasi0n post. This is the eagerly anticipated jailbreak for the jailbreak for the newest iOS release.
Ladies and gentlemen, the waiting is over! As we’ve just informed you, the evad3rs have released the eagerly awaited jailbreak tool called evasi0n that will set your iDevice free in just a couple of easy steps. Just as we did with Redsn0w, which allowed a tethered jailbreak for A4 devices running iOS 6, 6.0.1 or 6.1 beta, we have written an easy-to-use tutorial that will show you how to jailbreak iOS 6 on the iPhone, iPad or iPod Touch.
IIC also has a post with evasi0n download links.
