Abstract: A method and apparatus for using a mobile phone to customize user interface is disclosed. The method comprises first providing a default user interface screen on the mobile phone in a local memory. Upon power-up by a first user, the mobile phone displays the first user interface screen for a first user of the mobile phone. Then, the mobile phone can make a data call to a first web server through a global computer information network, e.g. the Internet. The phone can brows a first desired web page at the first web server. If selected, the phone duplicates the first desired web page to the local memory as the default user interface for the first user, such that when the mobile phone is powered up by the first user, the mobile phone displays the desired web page.
