k800i Camera Button Replacement?

Does anyone know any online shops that sell replacement side buttons for
K800i's? The camera button on mine has worn out and i can't get it to take
pictures anymore. (it engages focus but won't do the second click) I looked
inside and the pip on it has worn down.

I've had a look around but i've been unable to find anywhere that has the
side buttons. Most places only seem to carry the keypad. Does anyone know of
anywhere i can get one?

Many Thanks
