Siri

Siri is a voice assistant feature found in the iPad 3, iPad mini 1G, iPhone 4S, iPod touch 5G, and their successors. Siri has been present since iOS 5 (with the iPhone 4S) A 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) Any others ports are compatible with more iOS versions, but they're maybe unstable, slow, incompleted or scam. Almost all of them are illegal.

In iOS 6 (and above), Siri is supported by the 3rd generation iPad, 4th generation iPad, iPad Air, iPad mini 1G, iPad mini 2G, iPhone 4S, iPhone 5, iPhone 5c, iPhone 5s and iPod touch 5G.

Although other devices are capable of running Siri, they do not include the above files that are required for it to work.

Installation

An additional key in the capabilities section of /System/Library/CoreServices/SpringBoard.app/XXXAP.plist must be added for the device to enable Siri:

<key>assistant</key>
<true/>

An another key, "Raise to Speak" capability for iPhone only, that allow you to activate Siri when you raise your phone to your ear. (You don't need to add this key for iOS 5)

<key>siri-gesture</key>
<true/>

These keys can be added as capabilities in iOS 5 and 6 only, since the Model definition file is move along in iOS 7, in a DeviceTree instead.

The installation of Siri (its filesystems) on other devices requires access to the iPhone 4S (or supported iDevices) filesystem, to copy over the files above to a jailbroken device running the same iOS version, with correct files permissions. Then assistant is enabled in the capabilities plist (iOS 5 or 6) as above, and the device is rebooted.

Holding down the home button for a second should activate the Siri tray at the bottom of the screen (iPhone/iPod/iPad with iOS 5), or at the area close with home button on screen (iPad with iOS 6), but saying anything will make it says it can't connect. 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 a Siri-capable iDevices.

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 with iOS 5 also 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 edit the images to fix those by yourself.

Differently in iOS 6, assistant images are available both in Retina and non-Retina devices, due to the screen scale themselves, so you could copy the non-Retina images or artwork file from the jailbroken devices with non-Retina screen, it's iPad mini 1G, only one.

Changing Server

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:

192.168.1.5 guzzoni.apple.com

Make sure there is at least one blank line at the very end of the file, or this will fail.
