Apple seems to be disabling Siri on unsupported devices, Spire
Apple usually disables jailbreaks in new software releases. That is part of the reason why it took so long for Absinthe to debut for the iPhone 4S. It appears that Apple is also trying to break Siri running on unsupported devices, such as the iPhone 4. Many people who use Spire, the popular Siri port for the iPhone 4, have reported Siri is now disabled on their unsupported device. Has another cat and mouse game begun?
Historically, to get Siri working on an older device, you only need a server host and an iPhone 4S certificate. However, Apple apparently added a “SetActivationToken” that breaks services like Spire.
Just as quick, hackers have found a temporary workaround to get Spire working again. The fix is simply to delete “com.apple.assistant.plist” and the service should work again.
