UPDATE:- The best way of getting Siri on older devices is by using Spire. So please buy a proxy server and in my opinion the best Server is by Sirified. Please check it out on www.sirified.com. It is pretty fast and they also give 24 hour free trial and here is a video of it working.
UPDATE:-Video of it working and will be posting a tutorial on the blog as soon as we get 100 likes on our facebook page which is www.facebook.com/tech4lyf.
UPDATE-Got Siri working on iPhone 4 and iPod 4G!
Will be putting a tutorial soon. It's a legal port.
