Well that didn’t take long

Developer Steven Troughton-Smith has been working with 9to5Mac exclusively to port the iPhone 4S Siri voice command system to the iPhone 4. Troughton-Smith was able to get the beginning steps of a full port rolling after installing the iPhone 4S Siri and Springboard files onto an iPhone 4. As you can see in the video, Siri’s interface loads up with all the features from the iPhone 4S implementation.

Perhaps the biggest news here is that we’ve determined that there is no technical reason for Apple not to allow Siri to run on the iPhone 4. The iPhone 4 hardware can support the Siri artificial intelligence system, as the A4 processor is said to be powerful enough. We are not entirely sure why Apple is making Siri an iPhone 4S exclusive but it could be due to special microphone support, or because the A5 may allow it to run slightly quicker. After all, Apple is the company who blocked custom wallpapers on the iPhone 3G because the animation is slightly slugger than the animation on newer iOS devices.
