Siri, Please Contact Bob. “Are you Siri’iss?”
Siri isn’t just a simple piece of voice control software. To function properly, Siri must communicate with one of Apple’s servers for additional information. For example, when you ask Siri what the weather is like in Nashville, Tenn., it plays an elaborate game of telephone with a main database that has the information, and then updates you with the answer.
This is precisely the reason jailbreaking theiPhone 4 and the iPad to run Siri is so difficult.
