So now that Verizon has bailed on the Nexus One, I am thinking of switching from them to either AT&T or Sprint. (I know the Incredible is similar but I don't like the Sense UI and I want the fastest possible OS updates). My question is who has better overall coverage around the U.S. - AT&T or Sprint? I live 40 miles from Boston in Massachusetts and around New England is where the majority of my usage will take place. I do travel few times a year to other parts of the country though.
