Retina devices only.
biteLiquid is a black transparent theme for biteSMS. You need to view the screenshots to see its simplistic beauty for yourself. This theme keeps the iOS look and feel while adding dark and transparency throughout. Quick reply is fully themed. Give it a try, you wont be disappointed.
As shown in the screenshots, complete your iPhone's look by combining this with my Color Keyboard theme, "Android Black ColorKeyboard" and system theme 266hd.
