Over the weekend, we showed off Siri running on a jailbroken iPhone 4 and iPod Touch 4G thanks to the tireless efforts of iPhone hackers chpwn and Steve Troughton.

Clearly, Siri works just fine on lesser devices like the iPhone 4 and iPod touch, but despite this, chpwn and Troughton warned that we wouldn’t see an authorized release anytime soon. Now chpwn is clarifying why, and it’s just as the Dev Team warned us: Siri on non-iPhone 4S devices require piracy.

This could be fake, but it certainly looks real to us: iPhone hackers chpwn and Steve Troughton say they’ve gotten Siri working on the iPhone 4 and fourth-gen iPod touch, and they’ve got video to prove it. So it is possible. Sadly, though, both hackers say that whatever method they used for exploit is not for public release any time soon, so the rest of us poor suckers will just have to keep twiddling our thumbs.
