I imagine that headline sums up a pretty common course of action these days. I just dropped AT&T wireless, after 6 years of iPhone fun. Things had gotten a bit better following our move to the suburbs. Back in Chicago's Bucktown neighborhood, it was common to have no service whatsoever. AT&T explained that a cell tower had completely failed in our neighborhood, creating a "dead zone", and that there were no current concrete plans to repair it. And still, they offered no solutions whatsoever. No microcell, no equipment swap, no SIM replacement, nothing. Basically, a "deal with it" stance. Which is their prerogative.
