An untethered jailbreak is a type of jailbreak where your device does not require you to reboot with a connection to an external device capable of executing commands on the device.

Device support

Many device/firmware combinations can use an untethered jailbreak. The most current versions of iOS (3.2.2 and 4.1), as well as the iPod touch 4G, can be jailbroken already with limera1n.

Devices as new as the iPod touch 4G/Apple TV 2G have known bootrom exploits. However, the iPhone 3GS (old bootrom) and older have bootrom exploits that allow for an untethered jailbreak. Newer devices have bootrom exploits, but these are limited to a tethered jailbreak (without the assistance of a firmware-based exploit).

Utilities capable of untethered jailbreaks

These jailbreak utilities can perform an untethered jailbreak, sorted by operating system.

iOS

Star runs on the device itself, and is completely independent of a computer's operating system.

Mac OS X

Windows
