Q: Will this work on my iPhone 3GS?

A: Yes it will but the iPhone 3GS has horrible voice reduction therefore in loud places Siri will work very poorly.

Q: Will this work if I do not have a 4S?

A: Actually, yes. Read more here 

Q: How is privacy with a Siri server?

A: Any information passed through the device and our server is kept strictly confidential and not logged. 

Q: Is there ANY possible way to somehow port it to iOS 4? Also will also the 3G iTouch (with the headphones and mic) be compatible as well? I can’t upgrade to iOS 5 because I don’t have enough disk space on my PC.

A: Siri is most likely not going to work on iOS 4. Siri uses a lot of frameworks that are iOS 5 specific and it was not even compiled for iOS 4. The 3G may work with the right headphones but it may have some issues due to the missing microphone.

Q: Is this legal?

A: 100% don’t argue. Simple checklist: we do not redistribute copyrighted software, we do not use apple’s Siri server, and i4siri is composed of our work. 

Q: Can I get Siri if I don’t have a 4S?

A: Yes, if you use our servers you can. 

Q: Can I use Spire and just connect to your servers?

A: Simply yes.
