Methods and apparatus for the convenient arrangement of a user's address book according to intelligent algorithms. These intelligent algorithms, in one embodiment, take advantage of one or more of: (i) stored contact information associated with one or more users, (ii) stored geographic location information associated with the users and one or more contact entries in the user's address book, and/or (iii) stored voice and data communication information associated with the user. This algorithm arranges the entries in the users address book, using the stored information as an input, in an intelligent manner. In other embodiments, additional information is used as an input to the contact entry arranging algorithms such as, for example, entries in a user's digital calendar. Business methods utilizing the aforementioned methods and apparatus are also disclosed.
