Siri is a voice assistant feature found in the iPad 3, iPad mini, iPhone 4S, iPod touch 5G and their successors. Siri has been present since iOS 5 (with the iPhone 4S) A legal port to older devices has been completed by stroughtonsmith with the help of chpwn, and is available in Cydia as Spire. (Compatible only with iOS 5.0.1) There are other ports which are compatible with more iOS versions (iOS 5.1.1 through 7.x), but most of them are unstable, slow, incomplete, or a scam. However, the ports are not needed as of iOS 8; all compatible devices support Siri.

Installation (iOS 5 - 7)
In iOS 5 and 6, some additional keys in the capabilities section of /System/Library/CoreServices/SpringBoard.app/XXXAP.plist would be added to enable Siri:
<key>assistant</key> <true/> <key>siri-gesture</key> // Raise to speak, activate Siri when you raise your phone to ear (iOS 6) <true/>
Since the Model definition file is move along in iOS 7, in a DeviceTree instead. MobileSubstrate Hooking is required in order to inject these capabilities. (MGGetBoolAnswer(CFSTR("assistant")))
The installation of Siri (its filesystems) on other devices requires access to the iPhone 4S or supported devices filesystem, to copy over the files above to a jailbroken device running the same iOS version, with correct files permissions. The Siri capabilities are added as above, and the device is rebooted.
For iOS 5, the stock assistant images from the iPhone 4S are only available in Retina size. On non-Retina devices (iPad, iPad 2 and iPhone 3GS), this means many interface features may look different. The theme Siri Graphics for iPhone 3GS and iPad in Cydia fixes this.
Installing in iPad 3 running iOS 5 causes buggy interface, because the system usually forces the assistant window as full-screen (iPad and iPad 2 too), in that case you have to manually edit the images to fix that. Differently in iOS 6, assistant images are available both in Retina and non-Retina devices, so you could copy the non-Retina images or artwork file from the non-Retina jailbroken devices; it's for iPad mini.
Because some of Siri binaries are there, without them mean Siri won't work, this is the purpose of cache injection, to make Siri works.
- Copying /System/Library/Caches/com.apple.dyld/dyld_shared_cache_armv7 from Siri-capable devices.
- Placing it in some directory in your target devices, take note for the location.
- Editing /System/Library/LaunchDaemons/com.apple.SpringBoard.plist using some good text editor, by adding these section:
<key>EnvironmentVariables</key> <dict> <key>DYLD_SHARED_REGION</key> <string>private</string> <key>DYLD_SHARED_CACHE_DIR</key> <string>THE FULL LOCATION OF YOUR DYLD SHARED CACHE HERE (FOR EXAMPLE: /var/mobile/folder_with_dyld_shared_cache_inside)</string> <key>DYLD_SHARED_CACHE_DONT_VALIDATE</key> <string>1</string> </dict>
For iOS 6 and 7, both com.apple.backboardd andcom.apple.assistant_service deamon must be injected the code too.
- You have to find the proper Graphics driver binary for the ported devices because the cache also included that driver, specifically for that device. The cache we inject is commonly from Apple A5 devices, so the system won't be able to find the compatible graphics driver and causes massive animation lag if the target devices aren't iPad 2 or iPad 3. (Use the same driver with Apple A5 devices) (They don't need finding the binary) Apple A4 devices or lower need that, by copying binary named "IMGSGX535GLDriver" from Xcode-inside location:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS[THE iOS VERSION NUMBER].sdk/System/Library/Extensions/IMGSGX535GLDriver.bundle/IMGSGX535GLDriver
Into your target devices /System/Library/Extensions/IMGSGX535GLDriver.bundle directory. (Anyway, the graphics driver doesn't exist anymore in iOS 7 (and above) SDK)
- Save it and reboot the devices to take effect. Wrong cache location causes your devices not able to boot up. (Infinite SpringBoard crashing)
dyld_shared_cache injection usually slow down your devices, much in Apple A4 devices.
Purpose for iOS 5 devices
- Add missing binary at /System/Library/Assistant/UIPlugins/SpringBoard.assistantUIBundle/SpringBoard
Purpose for iOS 6 devices
- Add missing framework binary at /System/Library/PrivateFrameworks/AssistantUI.framework/AssistantUI
Purpose for iOS 7 devices
- Add missing framework binary at /System/Library/PrivateFrameworks/AssistantUI.framework/AssistantUI (Applied to SiriViewService.app and SpringBoard)
Holding down the home button for a second should activate the Siri tray at the bottom of the screen (iPhone, iPod and iPad running iOS 5), or at the area close with home button on screen (iPad running iOS 6), but saying anything will make it say it can't connect because the server rejects any query from these unsupported devices. This is due to the device requiring an identifier that the Siri servers generate every 24 hours for Siri-capable iDevices. SiriProxy can overcome this if you have access to those capable iDevices.
The server that Siri sends its data through can be changed in a number of ways. The most reliable method is to use a DNS server, as demonstrated by plamoni.
An easier approach is to edit the com.apple.assistant.plist file in the device's /var/mobile/Library/Preferences folder. It can be changed either on a jailbroken device with iFile, or via an iPhone backup reading utility. The hostname string simply needs to be replaced with the URL of your SiriProxy (i.e. your computer's IP address). This method could also allow for your SiriProxy to work outside of your Wi-Fi network, if you set up forwarding for port 443 to your computer in your router, and use your external IP address. However, some routers don't do port forwarding inside of their network, so you would need to change this setting yourself when you arrive or leave home. A static IP or dynamic DNS address (such as one from Dyn) is recommended.
The /etc/hosts file on a jailbroken device can also be modified. This can also be used externally, like the above method, though domain redirects are disallowed in host files, so a static IP is required. For instance, if you have a server which has the IP 192.168.1.5, enter this on a new line:
Make sure there is at least one blank line at the very end of the file, or this will fail.
It's possible to trick the server that you are using Siri-capable device, without any use of Siri proxy. By faking device model that the system would include as a "header" to send to Apple server (method -[ADAceConnection _startConnection] does that), as shown in SiriAuthFix.
