which icons exactly would you like? the theme installs the purple icons with it (or at least it should have) so i dont know which ones you want exactly.
and when you say folders, you talking about something like below, or something else. i would love a starting point for the folders, i can change colors fairly quickly and easily.
It won't let me attach the image from phone. But it is a partially open folder where front is a grey and back is purple. I have a red that came in a red gingerbread pack. Also its the icons in the liberty icon pack in the liberty toolbox, just purple instead of yellow.
The two I need most are folder icon and a handcent our light grey and purple messaging icon
for the future, i use an online image editor that is super easy to use. here is the link. this is the only thing i used to change these images. FotoFlexer
