It came as a bit of a blow to iPhone 4 owners when the iPhone 4S was released boasting the brilliant new Siri. Unfortunately, the Apple Gods did not see fit to bestow the new personal assistant feature on any of the iPhone 4S’ predecessors. Lucky for those iPhone 4 owners, there is a way to install Siri on your device running iOS 5.1.1.

Please note:

  • For the method to work, your device must first be Jailbroken. For help Jailbreaking your iPhone 4 you can follow one of our help guides HERE.
  • The actual install of Spite onto your device can take up to 20 minutes, for this reason ensure it is connected to WiFi.

Step 1. First you will need to add your Siri Repo to your iPhone 4. To achieve this you will need to open on the Cydia app and then navigate through the following:

‘Manage’ > ‘Sources’ > ‘Edit’ > ‘Add’

Then type the following into the URL that appears:

http://cydia.iphonetweak.fr

Then tap ‘Add Anyway’.

Step 2. Once the Siri Repo has been installed, you need to find Spite 3.0.1-1 (Untethered). You can find it by typing ‘Spite’ into the search bar. Tap on it.

Step 3. When it opens, tap ‘Install’ which you will find in the top right corner. Remember this can take some time.

Step 4. Once the installation is complete you will need to tap ‘Reboot Device’.

Step 5. When your device reboots you will first need to select a WiFi network. Then you need to tap ‘Use Siri’ > ‘Start Using Device’.

Step 6. Back in Cydia, search for ‘AssistantServer Installer’.

Step 7. When it opens, tap ‘Install’ from the top right-hand corner and let it install on your device.

Step 7. Once again, tap on ‘Reboot Device’.

Step 8. Now you have the necessary tools to use Siri on your iPhone 4 you must now enable them. Navigate to ‘Settings’ > ‘General’ > ‘Siri’.

Step 9. Switch Siri on.

Step 10. Go back to ‘Settings’  and locate ‘SiriServer’.

Step 11. Copy and write down the URL from the input at the top.

Step 12. Go back to ‘Settings’ and locate ‘Spire’.

Step 13. Now paste or type the URL from step 11 into the area marked ‘Proxy Host’.

Step 14. Go back to ‘Settings’ > ‘SiriServer’ and then tap ‘Start Server’.

Step 15. Exit ‘SiriServer’ and reboot your device.

You should now be able to use Siri on your device via the ‘Home’ button. If it doesn’t appear to be working you can try going back into SiriServer and pressing the ‘Update SiriServer’ button then rebooting it with a 10 – 15 gap before switching the device back on.
