thanks for your reply ian. i probably did install a few other programs at the same time but to be honest i cant remember what they were. unfortunately ive had to stop using the theme as the freezing problem keeps on happening and it is too much of a pain having to to turn the phone off/on, shame as i relly liked this theme.
as for flashing im too much of a newb to try that.
anyway i have installed the okuda system sounds and they are great and make the 900 sound really high tech, thanks for those.
