Vodafone (VOD) isn't happy with U.K. regulator Ofcom's decision to give rival Everything Everywhere (FTE, DTEGY.PK) the go-ahead to offer 4G services in the 1800 MHz. band, currently used for 2G/3G services. The approval means EE will get a head-start on Vodafone and other British carriers, who are planning to use 800 MHz. and 2.6 GHz. spectrum due to be sold in an auction early next year to deploy 4G.
