I don't know how to replace icons but I will learn and replace the white ones. Prefer a full gingerbread theme personally than a mix. That's what themes are all about though. Will you include the green in the extras zip? Also will v5 have a better 3g icon like that of v4? The new one appears too small and looks awkward. Other than those minor things for me the theme is looking great.
You are the man! Merry Christmas! Oh, and I too like the bat indicator seems to be the first thing people notice when playing with my phone as I convert them to custom users.
