Siri for iPhone 4, iPhone 3GS and iPod Touch 4th Gen on iOS6!
Here we are with the Siri Port on the iPhone 4 for iOS6!
Keep two things in mind.
One – It is in Beta
Two – It is not for the iPad!
First add this to your Cydia Sources – http://cydia.siriport.ru
Once the source is added, you open it up and scroll down till you see SiriPort (Original) iOS6
Once the package is installed, respring your iPhone, and go to the settings application.
You will see a new tab – Siriport.Ru Original
Click that, and then click Install Certificate,
It will take you to a Safari Page where you can install the certificate to Authorise the use of Siri on your iPhone 4.
Once that is done, you will have to open Redsn0w and reboot your device.
Because we are on a Tethered Boot, we will have to boot it from Redsn0w.
Once that is done, you will have to go back in Settings and go to General, and then Siri and turn it on.
Now there is a glitch, where you go back to the Siri section, it will show it as Off, but Siri is working dont you worry.
And well there you have it, Siri on A4 devices and below on iOS 6!
