A server device of a communication system provides a web interface to allow a user to modify user interface settings and contact information. The server device communicates the modified settings and contact information to the mobile communication device via a wireless communication network. The user interface settings can be communicated to the mobile communication device via the same wireless communication network that carries voice data. The user interface of the mobile communication device, as well as the stored contact information, can be updated without requiring the user to connect the device to a computer.
