Yes, that's revealed based on recent Apple patent fillings. Some new patent applications include event-based modes, scheduled and intelligent communications.
Event-based modes: As shown by above picture, your iPhone 4.0 device could be able to automatically adapt to different locations and life events and reconfigure it’s settings – e.g. switch the sound off and turn on a voicemail when calendar shows that you are in the meeting.

Scheduled communications: somewhat similar to the one above, but describes a way for you to automatically schedule/preset communications activities based on calendar events, your location, caller id and other conditions.

Intelligent communications: You can select appropriate communication modes for incoming communications requests based on a user’s preferences and availability. The device can determine the communication modes of a user based on the current activity and allow the user to provide customized information to his/her contacts.
Remember this is just a rumour. As we all know apple, one cant ever predict exact next move of apple
