In the first announcement in the UK, Hutchison 3 has announced that their network is live and that they expect to begin providing service by March 15, according to an article on BBC News.

3G is the next generation of wireless telephone technology that provides true high-speed communications (at speeds capable of handling reasonable quality audio and video).

Although O2 announced an operational network on the Isle of Man, "3" is the first widespread deployment of G3 services in the UK.
