On the weekend we saw a video of Siri ported to the iPhone 4, although Siri wasn’t working on the iPhone 4 due to the fact that it connects to Apple’s servers, and obviously the server would identify it as an iPhone 4, it also seemed slow and unresponsive.
Now the developer who has been working on the iPhone 4 port of Siri, Steve Troughton Smith, has posted another video of Siri on the iPhone 4, and it looks like he is making some progress with the iPhone 4 port, as it seems much more responsive than the last video
