Apple to bring official Siri app to older iPhones

Apple is reported to be testing a version of its Siri voice-activated digital assistant app that's designed to work on older versions of its iPhone, reports The Inquirer.

Siri was the centrepiece of Apple's new iOS 5 operating system, but allegedly required the dual-core A5 processor of the new iPhone 4S - launched at the same time - to work.

The appearance soon after of a jailbroken version of the app that had been made to work on the old iPhone 4 handset rather dented that claim - but even so, the announcement of an official version of the app that will work with older models will come as a relief to older iPhone users. Now those who can't afford the upgrade to the 4S, but who fancy getting in on the voice-operated action, can still do so without voiding their warranty.

It's worth remembering, though, that Siri was for a long time able to work on all versions of the iPhone. The original version of the app landed in the Apple iTunes App Store in February 2010, and was only pulled - after Apple had acquired the company that made it - in time to keep the voice-activated assistant as an exclusive selling point for the iPhone 4S at its launch.
