@sdk16420: I saw the other themes. The work done on it is impressive but I don't like them. They look too close of the stock theme (with the gray as major color...)
This is why I request some help to port my personnal favorite theme to my favorite phone
My only knowledge about theming is the replacement of the images... :/
@kormatoes: I tried to install CM7 on my Neo, but there is a hudge battery drain. So, no way for me to use CM7 for now...But I found the stock rom very good, responsive that's why I would keep it for now...
