Siri Works on Older iPhones

One less reason to buy the new iPhone 4S? Two hackers have reportedly cracked the exclusivity lock of the voice-command software Siri to make it work on the older iPhone 4 and the iPod Touch 4G. "I've tested pretty much every type of interaction you can make with [Siri on the iPhone 4]," Steve Troughton-Smith, one of the hackers, told PC World. "It works just as well as the iPhone 4S, and I've seen it work even faster than it at times." He is even planning to test Siri on the iPhone 3GS.
