20100232591 | Electronic telephone directory system - An electronic telephone directory system is described. Each entry in the directory has summary information, category specific information, and associated categories. The system displays a different view of the category specific information depending on categories associated with an entry. For example, a restaurant may have a detailed view that shows its menu and specials whereas the detailed view for a taxi service shows the company's coverage area. The directory periodically updates using cellular networks but generally operates without an active network connection. | 09-16-2010 |
