Sprint has begun rolling out 4G LTE network coverage to over 100 new cities in the US as part of a plan that it will carry out throughout the rest of 2012 and earlier 2013. Some of the major city areas that stand to get 4G LTE network coverage before any of the others include Boston, Chicago, Miami, New York, and Washington D.C. The company aims to have a US-wide 3G/4G network ready by the end of next year.
