New Yorkers wondering when Sprint’s LTE machine will finally find its way to the Big Apple can stop wondering – at least those New Yorkers living or working in the Bronx and Brooklyn. Sprint said on Wednesday that it is turning on its new 4G network in those two boroughs on July 30. The official New York launch is hardly a surprise given customers with LTE phones have been picking up random signals in the city, but officially bringing NYC online will be a major milestone in the carrier’s LTE rollout. New York is not only the most populated city in the U.S., but it is one of the most difficult in which to build a mobile network due to its extreme population density and strict regulations on where and how cell sites can be placed.
