Well i've searched for this problem and nothing came up so here we go.. The problem is the two aplications music and video. A little time ago i installed Iswitcher and went through a few of the themes i installed the icons of the theme called back in black. i didnt like it very much so i changed the theme to a different one. But the apps music and video stayed black (the black theme) i tried various things on Iswitcher, customize and Summerboard but have had no luck if you know the problem or have any suggestions please post.
