A portable multifunction device displays a first user interface object and a second user interface object on a touch screen display. Upon detecting a finger-down event at the first user interface object and one or more finger-dragging events on the touch screen display, the device moves the first user interface object on the touch screen display along a path determined by the finger-dragging events until the first user interface object at least in part overlaps the second user interface object. Upon detecting a finger-up event at the second user interface object, the device visually replaces the second user interface object with the first user interface object.
