P0sixninja details some of the background in a post on the Greenpoison blog:
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. Ten months ago, I myself was live tweeting from a tediously long line at the nearest Apple retail store, where I anxiously waited to become one of the world's first owners (& hackers) of the newly-released iPad 2.
Despite new tools to help with finding exploits they realized a team effort was necessary.
We finally admitted that the escalated obstacles presented by Apple's new A5 processor would not likely be overcome by one individual or team but all together, we should be more than able to conquer any challenges encountered. As such, a diverse group of iOS hackers all decided to set aside our personal goals & egos, relax our die-hard team loyalties, and pool our respective skill-sets, talents & exploits to form an iOS Super-Hacking "Dream Team."
The initial release is currently for Mac OS X only but Windows is coming soon! You can download it here.
