Nokia made the announcement at the 3GSM World Congress mobile phone trade fair in Cannes.
In a major about turn that will widen the market for its phones, Nokia also signalled it was willing to allow co-branding on handsets and to co-operate more with mobile operators.
"We have intensified our dialogue with operators...we have put our attentive ear to work like never before," said Olli-Pekka Kallasvuo, executive vice president mobile phones at Nokia.
Nokia unveiled three new phones at the show, including the 6681 which features a high-end music player with stereo output and a new software application.
