A report on Tuesday revealed that Apple has added a new barrier to the software needed to run Siri, a move that shows the Cupertino, Calif., company is actively tracking the growing number of iDevice users who have managed to port the voice-recognizing assistant to non-supported hardware.



From AppleInsider:

To get the voice-recognition software to work on other iOS devices, the so-called jailbreak community came up with a basic program called Spire which installs the required on-device files to communicate with the Siri servers. Spire's developers, the prolific hacker "chpwn" and Ryan Petrich, allege that the program is a completely legal port.

The software has caveats, however, as it is only available to jailbroken devices, requires a proxy Siri server and an iPhone 4S certificate.
