A method for accessing data contained in a data network using a mobile device or a different computing device. Common data may be accessed by both the mobile device and the computing device, with the mobile device communicating over a wireless data network and the computing device communicating over a data network such as the Internet, a private network or a network of public and private networks. A different format may be used to process and display the data on each of the two devices, with the data being converted as necessary for display on the devices. The data may be updated by the computing device and then made available to the mobile device.
