iPhone 4 running Siri!?

THIS video shows the Siri interface working on the older iPhone 4 model. However the creator of the Youtube video does still claim that they are unable to connect to Apple's servers. Essentially, at the moment there is no way of running Siri as it is intended to be used on the iPhone 4s, on an older model iPhone. It does ask the question though, why do Apple not release Siri to be used with the iPhone 4?!

Well the obvious reason would be that its a main selling feature of Apple's new "Most amazing iPhone yet", and by not giving iPhone 4 users access to the feature, Apple will hope to get customers to upgrade. The second idea as to why Apple will keep the feature exclusive to their latest bit of hardware, is because Siri on the iPhone 4 may cause even the very slightest affect on performance, which of course for Apple, would not be acceptable.

Also, not really post relevant, but a funny video I happened to come across ..
