The technology age is considered by many to be one of the most cold and impersonal. With communications devices that allow for so many people to interact without ever meeting face-to-face, this reputation might just be well earned. When it comes to cell phones, however, there are ways to help make the personality shine. Individualized cellular phone themes is one such way.
