Don't know what I'm doing wrong but still getting the white annoying backgroundyou can use htc themes along with my theme...
only some of them have white backgrounds
so if you still have that white background after going from settings - personalize - change theme and applying htc standard theme
i have no clue why
just rechecked the theme with and without fullscreen caller and dark dialogs option and its all good on my side...
did you install both rom and theme with international option or what carrier did you select ?
