AT&T has received a great deal of criticism for the abysmal quality of its network in major cities. They've always countered they they were going to, at some point in the future, upgrade the quality of service in those areas where it is poor. But according to their own SEC filings, they've actually been pulling back on spending on their network. All this time they've been taking more and more iPhone owners on unlimited plans, they've cut their spending on the network that is supposed to carry their data. Is it any wonder that people are so mad?
