Absinthe

Absinthe is the S5L8940 userland jailbreak tool for iPhone 4S and iPad 2 on iOS 5.0 (iPhone 4S only), 5.0.1 (9A405) and iOS 5.0.1 build 9A406 on iPhone 4S. This tool was released on January 20, 2012, and is available in three incarnations:

• A GUI tool with the same name, released by the Chronic Dev Team
• A command-line version by the iPhone Dev Team, in case troubleshooting is required
• A future integration with redsn0w

Exploit

The jailbreak packs Corona for the S5L8940 and the rest of the firmware patches in a regular iTunes backup and then restores this backup on to the device, which injects the required files. It is then completed by opening a web clip added to the home screen by Absinthe that uses an exploit in Safari to install Cydia.
