Apple has confirmed that it has no plans to bring its voice search feature, Siri, to older iPhone devices - stating that: "we currently have no plans to support older devices".

The news comes in from Michael Steeber's blog who had received word from someone who had contacted Apple with a bug report and had received a reply from Apple saying that Siri will only be available on the iPhone 4S.

"Engineering has provided the following feedback regarding this issue: Siri only works on iPhone 4S and we currently have no plans to support older devices."

Although this news won't come as a huge surprise to many users, there had been various attempts to port Siri voice recognition to earlier models and, according to some, there is no good reason why the iPhone 4 wouldn't be able to support it.

Siri, however, is still in its early stages and currently has a "beta" tag attached to it, so when certain issues are ironed out and, more importantly for Apple, the company has sold enough iPhone 4Ses; there could well be a change of heart at Cupertino.
