It's not clear when the Siri port will be released. Troughton-Smith said he first wants to confirm it works properly, is secure, doesn't break other apps, and functions on iOS devices. It's likely the Siri port will be available after a public release of iPhone 4S jailbreak tools.
But even once the code is released, porting Siri to the iPhone 4 and other iOS devices won't be for the faint of heart. Troughton-Smith said he plans to release source code to the tools he made, but won't create a compiled program to help you do the port. In part, Troughton-Smith is leery of creating a specific jailbreak tool, because it may be grounds for Apple to sue for copyright infringement since a complete Siri hack tool requires modifying and distributing system files taken from an iPhone 4S.
For Troughton-Smith, the Siri hack isn't really about creating the final tool, but solving the technical challenge presented by moving Siri to other iOS devices. "I wanted to prove to myself that I could make Siri work," Troughton-Smith said. "To make it easy for everyone else I'll leave to whomever takes the reins after this."
The iPhone 4 may not be the only device to get some unofficial Siri love. Troughton-Smith plans to test his solution on the iPhone 3GS in November.
