Chronic Dev Team has released a utility that can jailbreak the iPad 2 or iPhone 4S. It’s the first jailbreak utility available for devices with Apple’s dual-core A5 processor. Up until now all jailbreaking tools only worked on phones or tablets with the A4 processor or earlier chips.
The new tool is called GreenPois0n Absinthe and you can download it from the GreenPois0n website. It’s available for Windows, Mac and Linux.
The iPhone Dev Team also has also released a command line-based jailbreaking tool soon which walks you through the process one step at a time. It works on Mac or Windows.
This should help identify any remaining problem spots. Eventually the latest jailbreak tools will be incorporated in the next version of the popular redsn0w utility for jailbreaking iPhone, iPod touch, and iPad models.
Jailbreaking an iOS device allows users to install apps that aren’t available in the App Store including software which can change the boot logo, notification system, multitasking tray, or make other system-level changes to the operating system. It will also probably void your warranty.
Absinthe performs an “untethered” jailbreak, which means you can reboot your phone or tablet without having to connect it to a computer via a USB cable.
