evasi0n is a jailbreak tool that can be used to jailbreak (untethered) iOS 6.0-6.1.2on all supported devices, excluding both Apple TV 3G. It was first released on 4 February 2013 by evad3rs, and is available for Windows, OS X, and Linux (x86 and x86_64). There is also a Cydia package called "evasi0n iOS 6.0-6.1 untether" which can untether an existing tethered jailbreak without the need to restore and use the desktop tool.

Supported Devices

As of evasi0n's release, the only unsupported devices are the Apple TV 3G revisions, since the kernels on these devices lack an injection vector to run unsigned code. All other devices running iOS 6.0-6.1.2 are supported (including iOS 5.2 for the Apple TV 2G).
