Intrepid hackers have figured out how to port Siri's dictation capability, previously restricted to the iPhone 4S, onto the older iPhone 4 and iPhone 3GS handsets - once again giving users a reason not to upgrade to the new device.
A hacked copy of Siri's dictation code - but not, it's important to note, the software's much-vaunted 'virtual assistant' capabilities - forms the heart of Eric Day's 'Siri0us' app, which allows for full dictation on older iPhone and iPod Touch devices.
Available for jailbroken iOS devices via the popular Cydia service, the system doesn't require the use of the unique identifier from an iPhone 4S, meaning it will be significantly harder for Apple to block as it attempts to push users into an upgrade to use the app, which it once made available for all devices via the App Store.
Apple watcher iDownloadBlog has taken a hands-on look at Day's creation, and reports that it works well on an iPhone 4 and an iPod Touch 4G, while the site's readers have confirmed compatibility with the iPhone 3GS.
Android users are likely to be unimpressed, however: the vast majority of Android devices ship with a keyboard featuring a microphone icon that can be used to dictate text into almost any application, with no 'jailbreaking' required.
The hack does demonstrate still further that there is little reason for Apple to keep Siri an iPhone 4S exclusive, beyond a desire to see people ditch their perfectly usable handsets in favour of an expensive upgrade.
