Nokia’s Symbian operating system despite still remaining the most popular smartphone OS out there in the mobile space has come under some flak recently, and now word has it that the executive director of the Symbian Foundation, which is majority owned by Nokia, has thrown in the towel and stepped down.

According to an article over on the Boy Genius Report by Zach Epstein, the Symbian Foundation has announced that their Executive Director, Lee Williams has now stepped down from his position and been replaced by Tim Holbrow the former CFO.

The Symbian Foundation released this statement… “The Symbian Foundation is today announcing that Lee M. Williams has stepped down from his position as Executive Director for personal reasons. We thank Lee for his work over the past two years and wish him all the best in his future ventures.

The Board of Directors has appointed Tim Holbrow, formerly the Symbian Foundation’s CFO, to the position of Executive Director with immediate effect. We congratulate Tim and welcome him to his new role.”

Nokia isn’t a stranger to sudden high level exec shake ups as only last month Anssi Vanjoki their chief of Nokia mobile solutions resigned his post, and of course Nokia CEO Olli-Pekka Kallasvuo was replaced not too long ago by Stephen Elop.
