According to Intel, Seattle is now the most unwired city:

Seattle is now the most unwired city in America, according to Intel Corporation's third annual “Most Unwired Cities” survey released today. In a rapidly changing wireless landscape, Seattle narrowly unseated former top position holders San Francisco (2004's Most Unwired City) and Portland , Ore. (2003's Most Unwired City ). Seattle-area residents can now stay connected, informed and entertained throughout the city, from the original Starbucks at Pike Place Market and the Bank of America Tower to Seattle-Tacoma International Airport and the Space Needle.
