It wasn't very long ago that the US was considered behind most developed countries in wireless Internet tech. Oh, how the tables have turned. On Thursday April 19th, Verizon will add 27 new cities to its 4G network, with expanded coverage in another 44. According to its press release, this combined with other recent rollouts means that Verizon's 4G network will cover two-thirds of the US population - a staggering achievement considering that the service is less than a year and a half old. Verizon's first LTE device, the HTC Thunderbolt, launched just over a year ago.
