We already know that @chpwn and @stroughtonsmith have successfully ported Siri over to the iPhone 4. Many people now demand that they release their port or at least a description on how they did it. That’s why chpwn wrote a blog post on why they can’t release it right now.

For those of you who don’t want to read the whole text, here’s a summary. Basically, the reason why they can’t release it is copyright issues. As we already mentioned in an earlier post, you need files from an iPhone 4S. To get those files, you have to jailbreak your iPhone.
