If you use ADW launcher there's a pretty good theme in the market for a buck or so. Just look up adw themes and you'll find it. And if you want I'll post some screen shots......just ask
That would be the ease way. I am looking for something that will change the look. Right now I am useing UD2.3 with the new Christmas theme. I like how it changes the look of the apps and the stauts bar. If new how I would try it my self. I just don't realy know were to start or what I need to do.
