It's been ten days since Siri hit the scene and the virtual assistant is in the process of being torn apart by the hacking community. Siri, as it exists on the iPhone 4S, has been ported to the iPhone 4 and now the iPad 1. Developer Steven Troughton-Smith, who worked on the iPhone 4 port, has shared his progress with @jackoplane who has successfully ported the app to the iPad 1. Several images of Siri running on the tablet device document this achievement.
Unfortunately, neither the iPhone 4 nor the iPad port is fully functional at this point. Siri still needs to connect to Apple's servers to work and the servers are configured to accept requests only from the iPhone 4S. Potentially, these devices could be spoofed to look like an iPhone 4S which could open this functionality to jailbroken devices.
Jailbreaking and porting may be the only solution for owners of older hardware who want Siri on their iOS devices. It's doubtful that Apple will bring Siri to the iPad 1 or the iPhone 3GS. Apple may not want to support this older hardware and these models may also lack the processing power required for the voice assistant. But as some of you pointed out in one of our latest "You're The Pundit" posts, Apple could decide to bring Siri to the iPhone 4 and the iPad 2 once it comes out of beta.
