I don't have an iPhone 4s (yet) and I was wandering whether Siri needs Internet for absolutely all kinds of tasks or it needs Internet only when it has to look on the Internet for some info. For example if I'm not connected to the Internet in any way (Wi-Fi or 3G) and I say: wake me up at 7 o'clock, or remind me to do something or play the next song, what's gonna happen?
