If you are no longer be able to make Spire to works, then you are not alone! Many other non-iPhone 4s users who have their Spire installed experience the same situation too.
This is because Apple has blocked the said jailbreak tweak by adding SetActivationToken, this prevents from letting older and unsupported devices from entering or precisely tricking Apple’s server for allowing non-4s device using the company’s personal voice assistant.
So if you are one of the unlucky guy that relies on Spire in order to use Siri and currently being kicked out from communicating to Apple server, there is however a two temporary workarounds for you.
What you need to do to make Spire backs to work, now go to var/mobile/Library/Preferences/ use iFile or SSH and delete this file: com.apple.assistant.plist and then reboot your device. You will then see Spire work and getting full Siri access.
An alternative solution: Delete com.apple.assistant.plist and then turn off Siri for about 30 minutes, then restart your device, followed with turn on Siri.
Please remember, as I mentioned on the above paragraph that this is temporary workaround, certainly Apple will not let this one go forever, the company will certainly find a way to deal with it.
If you prefer an easy road you can download SARA as Siri alternative or using SiriPort to install Siri on iPhone 4.
Hope one of these workarounds work for you!
