[Guide] How to install Siri on iPhone 4

Siri has been ported to older iOS devices like the Apple iPhone 4 and Apple iPod Touch 4G. At the time of writing this guide Siri is fully functional on the devices mentioned above.

However since this process is not supported by Apple we cannot share the files required to complete this process. You can continue reading to find out how to install the Siri GUI on your device.



Siri was first introduced to the world on October 14th, at the Let's Talk iPhone event as a voice based assistant that will be featured on the Apple iPhone 4S. Users of older devices were left with just the new notifications system on iOS 5 to be satisfied with.

NOTE - It is important to note that this is not a full port of Siri and you wont be able to use the voice commands like you would on the iPhone 4s. The reason is that these commands are sent to Apple's servers to process the voice input data, and they do not accept data from iOS devices that are not the iPhone 4. This guide is for educational purposes only and should not be copied and reused for commercial purposes

Remember that you will be installing Siri only to test the visual elements of the software for now. If developers come up with an alternate way of getting Siri to work without having to communicate with Apple servers we will update you with that information

Please note that installing Siri on older devices is not supported by Apple. It may void your warranty and could possible affect the operation of your device. The process is meant for experienced users who understand the risks associated with this process
