It didn't take long. A self-proclaimed hacker has grabbed the much-touted Siri feature from iPhone 4S and moved it over to an iPhone 4. Apple chose to offer Siri, a talking personal assistant, only on its new iPhone 4S.
But Steve Toughton-Smith, who identifies himself as a developer, got Siri running on his iPhone 4 with "no problems," using files from an iPhone 4S, some validation tokens and a 20-step process.
Toughton-Smith even posted his successful hack on YouTube.
