Nokia has launched the first handset that also acts as a "walkie talkie," allowing users to speak immediately at the push of a button.
Nokia said the 5140 model would be available during the second quarter of next year. The phone's main feature, also called "push to talk," allows users to instantly speak to one or more people, with the service generating extra cash for operators on top of people's regular cellphone subscription fees.
