    Apple iPhone 4S Jailbreak, 10 Months in the Making, Now Available

      The Chronic Dev Team, a group of iOS hackers, has unveiled its GreenPois0n toolkit, a free download enabling Apple iPhone 4S and iPad 2 owners to jailbreak their devices. The download came at the cost of “thousands of hours of brain power and effort from a legion of world-renowned hackers,” the group said in a celebratory blog post.
      Apple dictates which applications can run on its devices and would very much like its operating systems to go un-manipulated. Jailbreaking is the process by which the system and user interface are opened up to user changes. Particularly alluring, jailbreaking enables devices to copy files without accepting the iTunes end-user agreement.
      The jailbreaking project has been in the works for 10 months-since Apple introduced its dual-core A5 processor in March 2011-and the team emphasized the rising difficulties it faces with each new product release. After months of moot effort, its success ultimately came when it decided to launch CDevReported software, enabling supporters to reroute the iOS crash reports normally sent to Apple to the Chronic Dev team instead. Accumulating more than 10 million crash reports in less than a week, the team was able to find a chink in the Apple armor and make its way in.
      The group released the jailbreak software earlier this month.
      Some caution that jailbreaking makes devices vulnerable to security issues such as viruses. Information Week pointed to a blog post by Sophos security expert Paul Ducklin, who wrote that “the only iPhone viruses ever seen in the wild (Ikee and Duh) were for jailbroken phones.”
      While it’s legal in the United States to jailbreak a phone, Apple asserts that doing so invalidates its devices’ warranties.
      “Hack the world!” Chester Winsniewski, also with Sophos, has blogged. “Just remember that you are on your own if you thumb your nose at the manufacturer of your device.”
      In December 2011, the Electronic Frontier Foundation submitted a formal application to the U.S. Copyright Office requesting that jailbreaking and circumventing digital rights management on mobile devices and video game consoles be legal.
      The application requested an exemption to the Digital Millennium Copyright Act, dispelling the “legal clouds” currently hanging over the matter.
      A jailbreak, for example, is currently available enabling Apple iPhone 3GS and iPhone 4 owners to install Siri, the voice-activated personal assistant that Apple offers exclusively on the iPhone 4S.
      On eWEEK.com, writer Don Reisinger cautioned against the install, writing that “all kinds of trouble can ensue.” For starters, he said, it could bring “security troubles galore,” as well as copyright violations. And heck, Siri’s not really worth the trouble, as it “starts to lose some of its luster” after the first week or so, Reisinger said.
      Earlier this week the Chronic Dev team posted a video of a jailbroken iPhone 4S that loaded properly, with Siri still intact.
      To run the new jailbreak, interested parties can download the zip file, attach their iPhone or iPad to a computer and click “Jailbreak.” The Greenpois0n software will do its thing.
      “After a few magical seconds,” writes the team, “Greenpois0n will display a -Complete’ message. At this point, the greenpois0n injection is complete-just wait for your device to reboot automatically.”
      When the device reboots and has an Internet connection, press the Loader icon, which will download and install a Cydia app. Reboot one more time, adds the team, and then enjoy.
