(Photo: Reuters/Robert Galbraith) iOS 5 Jailbreak: How to Install Siri on A4 Devices Using Spire and Free WordJelly [VIDEO]
For those of you wondering if there is a way to install Siri on Apple devices running the A4 chip (the iPhone 4, the iPhone 3GS, the original iPad and the iPod Touch), the Spire and proxy server techniques come to your rescue.
The project is better known as i4Siri and has been under development for the past few weeks. It is now available for free.
According to Cydiahelp, users should note that i4Siri is not a Siri port on to an older device but rather a smart Siri server, which needs Siri to be ported to the iDevice. The free utility based on Spire and Proxy server techniques does not require a registered iPhone 4S anymore.
Nevertheless, Spire needs the device to be running iOS 5. There may, in addition, be temporary bandwidth connection problems due to severe load on the i4Siri servers but it should work fine after a while.

STEP 1: First up, you need to jailbreak your device. In case you're on iOS 5.0.1, you can use our guide posted below for A4 devices and also iPhone 4S and iPad 2 to get untethered jailbreak. iOS 5.1 can be also semi-untethered jailbroken using the video guide below for A4 devices.
