It was a week of dramatic contrasts in the mobile phone industry. We started with Everything Everywhere’s news that 4G service was coming to the UK this year – possibly with a new brand that’ll work alongside Orange and T-Mobile. Meanwhile Three UK seems to have its own plans that involve acquiring some excess 4G spectrum from Everything Everywhere. There was much muttering from Vodafone and O2, although whether this’ll manifest itself as legal action remains to be seen.
