Dominic Sunnebo, of Kanatr Worldpanel, said “There are strong signs that WP7 Nokia handsets are starting to make an impact on the European smartphone market though US sales, where the Nokia brand is weaker, remain underwhelming. The fact that WP7 sales have overtaken Symbian based on one handset is encouraging; however, Nokia will need to expand the range quickly in order to keep up with the slew of next generation competitor products being launched in quarter two.”
