Vanjoki will stay on board another six months to finish up his current tasks, Nokia said. On Tuesday, Nokia World kicks off for a two-day event, in which the mobile giant will unveil its latest smartphones. Late last week, Nokia named Stephen Elop as its new CEO. It's an attempt to bring a software veteran in to combat advances by Apple's (AAPL) iPhone and Google's (GOOG) Android.
In a statement, Vanjoki said, "I felt the time has come to seek new opportunities in my life. At the same time, I am one hundred percent committed to doing my best for Nokia until my very last working day. I am also really looking forward to this year's Nokia World and sharing news about exciting new devices and solutions."
