If you're looking for an inspirational theme for your S60 phone, then give this one a try.
Sky Theme adds a vivid blue background wallpaper to your phone's home screen, complete with vibrant jets of light. A cool new blue color scheme is applied to the S60 interface, which matches well with the main image.
The Sky Theme also comes with some colorful new menu icons with a cartoony feel to them. While some may find these to be cheery, others might feel that they are a little babyish.
