Since Apple debuted the iPhone 4S with Siri voice controls, there has been speculation as to whether or not Apple will add the feature to older iPhones, but a report from iOS developer Michael Steeber has squashed those rumors for the time being.
In a blog post, Steeber cited a bug report thread from another person who contacted Apple and received the following response: "Siri only works on iPhone 4S and we currently have no plans to support older devices."
Apple reps did not immediately respond to questions about future plans for Siri.
Siri takes advantage of the dual-core processor and graphics chips in the iPhone 4S, something not available in older, single-core iPhones. Siri must chat back and forth with a server in order to provide users with answers to their questions or to follow various commands. As several memes have suggested, Siri hasn't figured out how to respond to every inquiry yet, but the product is technically still in beta and Apple has said it will improve over time. Hackers, of course, have already ported the service to other iOS devices via various workarounds.
Last week, Siri suffered a brief outage, but Apple hasn't discussed the glitch. For more, see How Apple Got the iPhone's Battery Problems Right, And Siri Problems Wrong.
