Since the release of the 4S, developers and hackers have attempted to make Siri work on the iPhone 4 (and other older iDevices). While successful in installing the digital assistant, they weren’t able to make Siri fully communicate with Apple’s servers. But it appears that a group of Chinese hackers (the CD-Team) has successfully ported the full functionality of Siri to jailbroken iDevices – the iPhone 4 and iPod Touch 4G in particular. Called H1Siri, the port – over a 100mb download – is found on Cydia via the Cydia.be and iphone3gsystem.fr/cydia repositories. While using Siri on your iPhone 4 is highly desirable no doubt, there are several red flags when it comes to installing the package. Aside from legality issues, this proxy hack involves sending your personal information to a third party server, which isn’t exactly desirable to say the least. But if you still want to give it a try, a step-by-step tutorial showing you how can be found here. Below is a video of a youtube user running H1Siri on his iPhone 4.
