I had to uninstall like 12 apps because they wouldn't work. I have absolutely no idea what happened. When I add things into customize, and I try to change the look of my iPod, it won't do it. I'm stuck with what I have. I can still change my summerboard themes, but yeah. I'm just gonna rejailbreak. But, I'm posting this to keep others alert that if this happens, I'm still looking for the answer.
