iPad 2 owners who have been longing to jailbreak their units can finally do so using Comex's jailbreakme. The jailbreakme.com site relies on an exploit that crashes Safari, allowing custom code injection to create the iOS jailbreak. The site was first used way back in 2008, and again in 2010, to provide an incredibly user-friendly approach to jailbreak.
Jailbreak allows users to gain full root access to their devices, letting them install third party software outside of Apple's app store system and to leverage full Unix command line access. While not for everyone, the Library of Congress has affirmed that jailbreaking is legal. Jailbreakme exploits inevitably patch themselves, so the device becomes (admittedly, somewhat ironically) more secure after the exploit than before.
To perform the jailbreak, visit jailbreakme.com from an iOS device.
