VODAFONE, the largest mobile phone operator, is promising a 'phased introduction' of video and music downloads for its 3G system, which should go live later this year. It will unveil a package of new-style applications ahead of the launch when it outlines so-called global data services, designed to work on GPRS (2 1/2G) and 3G networks, probably in the autumn. Vodafone guarantees the minimum service level at the fringe area of a network will be 64kbps, just enough for video.
