With their expansion on August 16th they have 371 markets.
for the record Verizon has always stated they were going to have at least 400 markets covered by the end of 2012. Well it's August and they are at 371 and each month they have a major expansion of at least 30 new markets. So Verizon should reach that 400 market total in September 3 months early and could be at 500 markets by the end of 2012.
