Abstract: A method for processing a user interface in a mobile station comprises segregating application program data for constructing the user interface such that content data is separate from display style data, and storing the segregated application program data. The method also comprises constructing the user interface such that the content data corresponds to the display style data, and converting the format of the content data using the display style data. The method may further comprise displaying converted content data. The method may further comprise segregating application program data for constructing the user interface such that the soft key data is separate from the content data and the display style data. The display style data may comprise style sheet data.
