Well well well, don’t get your hopes up! Yes, below we’ll show you how to install Siri on your iPhone 4 and iPod touch 4G but you won’t be able to use it. Just like all hackers who ported Siri on older devices, you’ll only get Siri GUI on an iPhone 4, iPod touch 4G and other devices running iOS 5.

You’ll need to download some extracted files from the iPhone 4S. You’ll surely need to put them on your iPhone 4, iPhone 3GS, iPod touch 4G, iPod touch 3G to be able to get the GUI.

Again, it’s just the GUI and you won’t be able to talk to Siri since it won’t be connected to Apple’s servers. Also please note that we’ve tried the method and it’s working.
