I have downloaded a couple of themes off here. Some of the themes work fully. Some of them, unfortunately the ones i really like, work on all the icons. but the wallpaper thats supposed to be there does not show. instead, the car picture that i have set for when i open my ipod to the slide screen comes up after i slide and therefore i cant read any of the text under my apps because its written in white. I was wondering why this is happening. Please help.
