A couple weeks ago we attended a Webinar held by O’Reilly and presented by Jonathan Zdziarski titled iPhone Forensics 101: Bypassing the iPhone Passcode.  During the Webiner, self proclaimed iPhone hacker Jonathan Zdziarski, guided us through the steps used by law enforcement agencies to bypass the iPhone 3G’s passcode lock by creating a custom firmware bundle. To say that we were impressed by the presentation is simply an understatement.

While the event might not interest the majority of iPhone users out there, it is a solid foundation for anyone looking to take their iPhone knowledge to the next level.  For a bit of background, Jonathan is also a full-time research scientist and longtime mobile hacker. Prior to the iPhone, Jonathan was well known for uncovering vulnerabilities in Verizon’s online systems and hacking popular Verizon phones to restore functionality once crippled by the communications behemoth. His books include iPhone Application Development and iPhone Forensics.
