Thunderbolt has been waiting for. Verizon today announced the addition of 21 new markets to its LTE coverage, starting June 16th. The list includes some biggish spots, like Boise, ID, Milwaukee / Madison, WI, Salt Lake City, UT, and Hartford, CT -- Northern California will be getting a major coverage boost, as well, with the existing Bay Area coverage being expanded to Marin and Solano counties. The network launched with 38 markets back in December and those, plus these new additions and a handful announced earlier this month, are bringing the company ever closer to its proposed 175 markets by the end of the year. That's a whole lot of green stars.
