RIM is back with more free BlackBerry themes! You may recall back in December they released free Christmas themes, and more recently they released a theme for those with visual disabilities. This time around they have published two lovely spring themes, Roots of Spring and Spring Blossom. Roots of Spring has a sweet tree wallpaper and flowers and suns sprinkled throughout. Spring Blossom has a pastel BlackBerry wallpaper and a more subtle look throughout. Icons in both themes have a glow to them, which is a warm touch. You can download these from BlackBerry App World for free! They're compatible with most BlackBerry smartphones.
