Well known and respected developer chpwn has finally released first legal Siri port to public for older generation iOS devices. Dubbed as Spire, the port allows iPhone 4, iPhone 3GS, iPod touch 4G/3G and first-gen iPad users, jailbroken on iOS 5, to run Siri, which has official been available only for iPhone 4S users.
Siri is one of those features everybody loves to have on their iDevices including iPhone, iPad and iPod Touch. Fortunately, we have found a successful port which will give you the complete GUI and the connection with Apple servers. If you would like to port, fully working Siri on your iPhone 4 (GSM/CDMA) and iPod Touch 4G follow our instructions below. Please note that the Siri port is currently available on iPhone 4 (GSM/CDMA) and iPod Touch 4G so anyone who is using iPhone 3GS, iPad 2 or iPad 1, or iPod Touch 3G will not be able to get their hands on this port.
