Research Triangle Park, NC – May 8, 2007 – Sony Ericsson today announced a new phone born out of our design teams’ love for the materials and colors found in the natural world. The Sony Ericsson S500 is a 14mm slim slider offering color accents and changing desktop themes. You set the in-phone themes and external light effects to change when you want - with the seasons, as day turns to night or when the weekend begins.
