SARA is based on Spire tweak but does not require to utilize Siri proxy to make it works, just like SiriPort.
And it is supporting the following iOs devices models: iPhone 3G, 3GS, iPhone 4G, also iPad 1 and 2, iPod 2G, 3G and iPod touch 4g.
This can be a good alternative, if you are unable to get Siri proxy or failed to follow the guide to install Siri on iPhone 4 using SiriPort.
Anyway if you are interested you can get SARA by launching Cydia from your device, and add the URL repository: http://isoftjsc.com .
