The iPhone 4S officially went on sale yesterday, bringing record sales numbers for Sprint and record activations for AT&T. One of the more notable features of the device is Apple’s new Siri technology.
Although the technology was originally slated as an iPhone 4S exclusive, Steve Troughton Smith has managed to port it to the iPhone 4! 9to5Mac has uploaded the following video showing it in action.
Details have yet to be published about when the port will become publicly available.
