Ok so we’ve got word that there is finally a way to install Siri on your non iPhone 4S devices, such as the iPhone 4 and the iPod Touch 4G. Unlike all the other mods out there this tweak will allow you to run Siri without the need for a Proxy. So lets get right down to it. You will need to be jailbroken so if you haven’t yet, check our jailbreak chart.
Now here is the step by step.
1. Start Cydia and add repo.siriport.ru as a new source. If you need help, click “how to add a cydia source”
2. Once your source is added and cydia refreshes, search for Siriport and install it.
3. Restart your device.
4. Goto this link “http://www.jailbreakmatrix.com/images/Certificate.crt” on your iDevice and install the certificate
5. Reboot your device
6. Hold the home button and activate siri, and say “Hello Siri”
It may take a few min to activate
Enjoy
