Thus, it's possible to
say, send a phone theme file of a CD cover,
together with a ringtones
of one of the songs in the CD in just a single
file. A single theme package can
contain graphics for one or many changeable
components. If a theme package does not
contain a new component, the default UI
graphics are shown.
Changing a theme only affects the look and
feel of the UI. The functions or features of
the device are not changed. .
