Abstract: A method for configuring a mobile phone to have consumer selected functions includes the steps of: designing application software having different functions; collecting the designed application software into a database; selecting predetermined application software having desired functions from the database; and inputting the selected application software into corresponding storage devices of a mobile phone; Thus the mobile phone has the functions that the consumer wants. Application software can be reconfigured and upgraded when the consumer has some new or higher demands for functions. The high cost of purchasing a new mobile phone is thus avoided by the consumer when the consumer wants to upgrade functions.
