The iPhone Dev Team released version 2.0 of the Pwnage Tool, which allows you to jailbreak iPhones and iPods running the new iPhone 2.0 software. It also unlocks first generation iPhones, allowing them to be used on any mobile phone network, but won't unlock the new 3G model (yet).
You can find links for downloading the Pwnage Tool, as well as some instructions to follow if you run into problems using it on the iPhone Dev Team blog.
