I don't see how AT&T ever spent that much... their network for the last 5 years or so has always been the least reliable.... Sure they and T-Mobile are the only ones with dual data stream networks, but AT&T can barely send MMS messages if I remember right? And I don't know how many times I hear people complain about the dropped calls and lack of 3G coverage/reliability... My buddy who constantly goes from Indiana, to Texas, to New York to see family says that as soon as he leaves home he starts having major issues with getting 3G.
They really did spend that much. The main thing with AT&T was spreading out as much service as possible, not just focusing on 3G. And AT&T has no problem with sending MMS, it was just the iPhone that wasn't supported for some odd reason.
3G coverage does not equal coverage in general, and a few years back VZW was a LOT worse off than they are now. They have been pushing out EVDO in as many areas as possible without actually beefing up the network structure past that.
Lately, VZW has been pulling ahead after the acquisition of Alltel, that really pushed them forward a lot. They had more leeway to introduce a wider 3G coverage to the country, while AT&T was still focusing on covering more areas than beefing up their network.
Now, I'm not excusing the fact that AT&T has been spending less money to work on their network, because that's just crap. They should be putting at least as much into their network as they used to.
I think ever since the whole confusing acquisitions/takeovers between Cingular and AT&T, that the AT&T thing was a turn for the worse. I started working for them right at the time they had become AT&T, and got the last dregs of the old customer service folks and service before they switched it out with AT&T's horrid service. They were much better a few years back as Cingular.
Summary: VZW is a great company, but they aren't mystically better than AT&T. They have their own issues with the way they handle business and customers, and the way they spread their coverage. I just think that AT&T needs to fire De La Vega, and finally get their heads out of their collective asses, and stop letting the iPhone sales go to their heads.
