I decided I did not like the bricks in my previous black dialer so I turned to photoshop and came up with this:
Before:
After:
If you use it, please hit thanks
UPDATE: New incall screen to match and a mute button to match if you're using the black slide to answer
UPDATE 2: Complete version posted which also enables slide to answer/ignore. Works fine but some people have had problems with it and sometimes are unable to uninstall so use at your own risk
UPDATE 3: Apparently, doesn't work too well with non s2a dialers. If someone has the original phonecanvas, let me know so I can skin that too
