250 Million 3G VoIP Users by 2012, According to New Research

The first full VoIP mobile phone (3SkypePhone) has only just been launched but already a professional research agency is forecasting that there will be 250 million users of 3G VoIP by 2012, compared with less than 100 million for voice on Wi-Fi. Considering how new VoIP on 3G is it strange to think that it will be more popular than VoIP via Wi-Fi.
