Evasi0n

evasi0n is a jailbreak tool that can be used to jailbreak (untethered) iOS 6.0-6.1 on all supported devices, excluding the Apple TV 3G. It was releasd on 4 Feburary 2013 by its developers, evad3rs, and supports Windows, OS X, and Linux (x86 and x86_64).

Supported Devices
As of evasi0n's release, the only unsupported device is the Apple TV 3G, since the kernel is still missing a injector vector to run unsigned code. All other devices on iOS 6.0-6.1 are supported (as well as iOS 5.2 for the Apple TV 2G).

1.0
Version 1.0 was released on 4 February 2013. This version contains a bug that causes the Weather app to not work. The Notification Center widget is unaffected.
