Okay so there have been countless “solutions” which work for sometime and then go berserk. Siri on any other device other than an iPhone 4S looked almost impossible, right?
Then came Spite. That worked for sometime but then it became problematic. Now, there’s some mix and match and an update to all that and we have a fully-functional Siri on any iDevice of your choice (non-A5 chip device) running any version of the iOS (5.x).
Let’s cut the chase.
Here’s what you’ll need to install Siri on iPhone 4 iOS 5.1 / 5.0.1 / 5.0 (or on iPhone 3GS, iPod Touch 4G, iPad):
Jailbroken iDevice. We’ve already posted on how to jailbreak iDevices running iOS 5.x

https://i4sirifree.mooo.com/ -(a Proxy server we’ll use later)
So, let’s get started: (instal Siri on iOS 5.1 / 5.0 / 5.0.1)
1. First off, open Cydia on your jailbroken device. Add the repo mentioned in the first link to the Sources option in Cydia.
2. Now, find the app ‘Spire’ and install it. You will need to wait a while because that’s a 150 MB package which you are downloading.
3. The app requires a reboot. Do that.
4. Once you’re done with rebooting your iDevice, head to Settings → General → Siri. Turn it on.
5. Now, head back, and tap on Spire (under Settings). You will have to add this link in the proxy text box: https://i4sirifree.mooo.com/
6. Now, just point your Safari browser (from the same iDevice) to the third link we posted. http://i4siri.com/installcertificate.html
7. The last step will create the valid Certificate for your iDevice to be recognized as an authorized device by the Apple’s servers when you use Siri.
That’s it. You can now start using Siri like you’d on an iPhone 4S.
Most of the users have reported that this method works perfectly well, although it’s a bit slow. Also, the method has worked well on all kinds of iDevices mentioned above that have been jailbroken (tethered / semi-tethered / untethered).
