AT&T contacted TiPb with a statement refuting claims that their capital expenditures, specifically their investment in wireless infrastructure, has decreased while at the same time their data revenue is increasing.
To quickly recap, the claim about infrastructure investment falling as data profits rose was one of the most direct charges leveled by Newsweek's Daniel Lyons (writing as Fake Steve) as part of his Operation Chokehold series, and repeated several times on TiPb and other sites.
In the statement (reprinted in it's entirety below) AT&T claims they've increased network investment in 2009, and are taking other steps (like rolling out the 850 MHz band) to improve customer experience.
Remaining unaddressed: the actual cause of the iPhone-on-AT&T problem(s) in cities like New York and San Francisco. Granted, users in those or other affected areas may not care why it's broken. However, they likely do care deeply that it gets fixed and soon. (And so should AT&T given the increasing level of mainstream attention).
So, read the response below and then let us know what you think.
