George Hotz, the man who brought you the jailbreak tool purplera1n, has once again impressed us all and this time it's an all iPhone 3.1.2 jailbreak only solution, blackra1n. Mac users need not apply as blackra1n is currently a Windows only application.
blockquote>So, what is blackra1n? blackra1n is a 30 second ALL device 3.1.2 jailbreak. Even the ipt3, but the ipt3 is tethered. In order to boot it, just rerun blackra1n. As far as donations go, they are much appreciated, but not until after blackra1n works for you. I never ask for donations before the tool is released.
