As the name says, it’s the PC tool for creating themes for S60 devices, allowing user to manage the appearance of wallpaper, application icons, color schemes, or any other UI component. Once a theme has been created, the S60 Theme Studio will package it into a Symbian OS installation file.
Version 3.0 adds support for S60 Platform 3rd Edition, including morphing themes, animated effects, Music Player themes, and support for multiple resolutions (352 x 416, 240 x 320, and 176 x 208 pixels).
