You can't do an untethered jailbreak.
Tethered jailbreak is disponible but not practical.
Hope you understand the difference.

Apple already pushed out iOS 6.0.1 that repaired four new critical security issues and almost 200 security vulnerabilities.

The most usefull vulnerability for an untethered jailbreak was a kernel flaw discovered by researcher Mark Dowd of Azimuth Security and Eric Monti of Square that affects iPhone 3GS and later, as well iPod Touch and iPad2 and later. An attacker exploiting the vulnerability could essentially bypass address space randomization layout (ASLR) protections using a malicious application, and could determine addresses in the kernel.

If someone lucky find how to bypass ASLR we will see a new jailbreak tool in the next months, but only for the coming iOS 6.1
