Earlier tonight we told you that hackers Chpwn and Ryan Petrich released a legal port of Siri called Spire for older models of the iPhone, iPod Touch and iPad. The Spire Cydia tweak is an extremely easy way to install Siri on the iPhone 4, iPhone 3GS, iPod Touch 4G, iPod Touch 3G and first generation iPad. Unlike previous ports of Siri, like the H1Siri Cydia tweak, that are unreliable and buggy, the Spire Cydia tweak is very stable and is actually legal. This is because Spire downloads the necessary Siri files directly from Apple’s servers and allows you to specify your own proxy server, rather than one public proxy server. While this may sound all great, there are a few catches to the Spire Cydia tweak that are mentioned below:

Requirements:

1. Jailbroken iOS Device tethered (NOT semi-tethered) running the iOS 5.0 or iOS 5.0.1 firmware (more info).
2. An iPhone 4S or access to a friends iPhone 4S to obtain 4 unique keys – assistantID, speechID, validationdata and finally x-ace-host (more info).
3. A Siri proxy server (more info).

If you would like to learn how to install the Spire Cydia tweak to use Siri on your older iPhone, iPod Touch or iPad then you can follow this Spire how to guide from iJailbreak.com.

How To Install Spire Cydia Tweak

Step 1) – The first thing you will need to do is Jailbreak your iPhone, iPod Touch or iPad running the iOS 5.o or the iOS 5.0.1 firmware. To do this please visit iJailbreak’s official Jailbreak Section where you can find an applicable Jailbreaking guide for your iPhone, iPod Touch or iPad.

Note: At this time the Spire Cydia tweak is not compatible with the Semi-Tethered iOS 5/iOS 5.0.1 Jailbreak.

Step 2) – Once you have a Jailbroken iDevice running the iOS 5.0/iOS 5.0.1 firmware you will need to launch Cydia from your SpringBoard (homescreen).

Step 3) – With Cydia up and running you will need to go into the Search tab and type in:

Spire

Step 4) – When you see Spire come up on Cydia’s search results you will need to click on it, read through the warnings/descriptions, and then install it to your iPhone, iPod Touch or iPad.

Note: The Spire Cydia tweak uses about 100 MB of data, so please connect to Wi-Fi before installing.

Step 5) – Once the Spire Cydia tweak has been installed to your iPhone, iPod Touch or iPad you will need to reboot and then obviously boot tethered using a Jailbreaking tool like RedSn0w.

Step 6) – Upon rebooting your iDevice into a usable state you will need to launch the Settings.app and go into the Spire tab.

Step 7) – From the Spire tab in the Settings.app you will see a text area to enter a Proxy Host. This can be a proxy host created by you (as explained in the Requirements section at the top of this how to guide), or a 3rd party proxy host that you have access to.

Note: As I mentioned previously, if you wait a few days I am sure people will start to release URL’s to their Proxy Servers for people to connect to. Please check our Spire Porxy Server list section by clicking here.

Step 8 ) – With the Spire Cydia tweak now configured properly you should be able to use Siri on your older iPhone, iPod Touch or iPad.

Note: As pointed out by helpful people in the comments section below, in order to get rid of Voice Control and enable the Siri GUI. You will need to first go into the Settings.app, then the General tab and finally into the Siri tab. From here you can actually enable Siri and disable voice control.

Congratulations! You have just installed the Spire Cydia tweak to your older iPhone, iPod Touch or iPad. Don’t forget to share any questions you may have or relevant thoughts in the comments section below and follow us on Facebook, Twitter or Google+ for more updates if you have not already.
