Summary Box: Nokia mobile phone exec resigns

THE DEPARTURE: The head of Nokia Corp.’s mobile solutions business, Anssi Vanjoki, is resigning, just three days after the handset maker appointed a new CEO in its bid to become more competitive.

THE BACKGROUND: Vanjoki is in charge of top-end mobile phones — an area Nokia is keen on improving as it tries to rival Apple Inc., Research In Motion Ltd.’s BlackBerrys and Google Inc.’s Android software

WHAT’S AT STAKE: With Nokia stock down more than 20 percent this year after two profit warnings, the company’s management has come under increasing pressure from investors.
