A hacker recently announced the availability of a tool designed to enable use of Siri on an iPhone 4.

"Owners of Apple’s iPhone 4 who have a hankering to use the company’s much-publicized voice-recognition personal assistant Siri can now do so thanks to a download designed by a hacker known as 'chpwn,' who posted the details of the program on his blog," writes eWeek's Nathan Eddy. "The tool, Spire, will download Siri itself (directly from Apple) while it installs."

"However, Spire is not a complete solution," Eddy writes. "Apple still requires authorization to use Siri, so information from an iPhone 4S is still required."
