Of course I’m dying to have Siri on my iPad 2. But Apple’s official line, reiterated in a report on Cult of Mac, is that Siri will only be available on the iPhone 4S. Responding to a query from the website, an Apple engineer said. “Siri only works on the iPhone 4S and we currently have no plans to support older devices.” Of course, the optimists among us focus on the word “currently,” hoping that it’ll happen in the future. Despite Apple’s rationale that older devices aren’t powerful enough to run Siri, hackers have been able to show that it can run on older phones.
