How to Install Siri on a Jailbroken iPhone and iPod Touch
Spiri is a new hack for jailbroken iPhone and iPod Touch that allows you to run Siri, the voice assistant. The hack is compatible with jailbroken iPhone 4, iPhone 3GS, iPod Touch 3rd generation, iPod Touch 4th generation and iPad 1. Created by Ryan Petrich and Chpwn, this hack will allow you to enter your own proxy server address to obtain files required by Apple to grant you the authorization to use Siri.
The Siri hack “uses a new method to obtain the files necessary for Siri, so it doesn’t have the copyright issues encountered by previous attempts”. Cpwn, the developer, explains that the app directs “all traffic through a specific proxy server (and the associated privacy issues), Spire allows you to specify your own proxy server”.
To install Siri on your jailbroken iPhone or iPod Touch you need to get a proxy. Chpwn has provided several ideas on how to do that, including owning an iPhone 4S or using a friend’s authentication tokens for iPhone 4S.
Another solution if you want a voice assistant like Siri on your jailbroken device is to replace Siri and try a similar service like Google Chrome’s speech API via the tweaks NowNow or Activoice. This is also the case if you’re running a more recent iOS firmware such as 5.1 or 6.x.
Spiri, the hack for Siri is available for free in the Cydia app store and takes only 100 MB.
