A system for adding or updating contact data in a wireless communication device, cellular telephone, pager or personal digital assistant (PDA) is shown. Contact data associated with actual or potential communicants may be entered into a database in the wireless communication device using a detachable input interface, a touch display, a personal computer or a wireless receiver. The contact data may include name, telephone number, fax number, address, email, image or sound data associated with actual or potential communicants. In one embodiment, data may be entered or modified from a detachable keyboard while viewing a cursor location that is presented within a small touch display in the wireless communication device. The wireless communication device may include a cellular or paging link and can receive Caller ID data originating from the public switched telephone network over a wireless communication system.
