Hacker cracks Apple's latest iPhone 3GS security measures

A hacker this week released a new exploit that allows users to circumvent Apple’s preventative measures that have blocked unauthorized code from being run on the new iPhone 3GS.
In October, Apple unexpectedly began shipping new iPhone 3GS models to ward off hackers who run unauthorized software in a practice known as “jailbreaking.” In addition to unlocking the handset for use on other carriers, the practice can also be used to run unsigned code.
Hacker George Hotz this week released “blacksn0w,” a combination jailbreak and unlock tool that works for the iPhone 3G and iPhone 3GS. The free software is noteworthy because it is the first known successful jailbreak and unlock for the iPhone 3GS with iPhone OS 3.1.2 and baseband 05.11.07.
Apple updated the BootROM for the iPhone 3GS to iBoot-359.32 in with a mid-cycle hardware release in October — the first time ever that the handset maker had modified its hardware in the middle of a product line, without a new model released.
Hotz is a teenager who made headlines two years ago when he was the first to successfully unlock Apple’s original iPhone all by himself. This summer, he also released the first jailbreaking tool for the iPhone 3GS.
