Developer Ryan Petrich (with help from Steven Troughton-Smith and chpwn) has ported the Siri artificial-intelligence system to the iPhone 3GS. The port seems to work well based on the video, but we’ve been told that the microphone performance is significantly worse than the iPhone 4 microphone’s performance. If there is any significant ambient noise, the home button needs to be clicked to stop voice input. http://9to5mac.com/2011/11/07/siri-...c-MacAllDay (9 to 5 Mac - Apple Intelligence)
