Themes provide the mobile phone with changeable characteristics pertaining to the appearance and sound presented by the mobile phone. A theme profile associated with the mobile phone contains data pertaining to which theme to apply to the mobile phone and when to transition to another theme as well as where theme content data is located. The mobile phone then waits for a triggering event to occur. When such a triggering event occurs, it causes a transition from the currently active theme to another theme. A new theme based on an associated triggering event is applied to the mobile phone changing its look and feel.
