At Long Last, Modders Roll Out Untethered Jailbreak for iPhone 4S and iPad 2
"The ridiculously complex combination of exploits-within-exploits that make this iOS jailbreak possible have consumed thousands of hours of brain-power & effort from a legion of world-renowned hackers, several of whom have been working diligently on this project since the dual-core A5 processor was unveiled by Apple last March," the Chronic Dev Team said.
What ultimately proved most fruitful for the team of hackers were crash reports submitted CDevReporter, which they described as "an invaluable source of information for iOS hacking & research."
Jailbreaking, if you're not familiar with the term, allows users to run unauthorized software on their devices, but it can also potentially open them up to security risks. In any event, if you want to jailbreak your iPhone 4S or iPad 2 device, be sure to first update your software to iOS 5.0.1, and then download GreenPois0n Absinthe v0.2 for Windows or Mac OS X (Linux is coming soon).
