Week 2-AT&T Claims to have Improved Service

AT&T Boasts of Billions Spent on Network Improvements
As an AT&T customer this article caught my eye.  I regularly have trouble with dropped calls, unexplained loss of service, and let's not mention the issues on game days.  So I was very interested to see what AT&T was going to do with these billions of dollars to improve their service.  I was disappointed to find out that much of this money has already be spent on putting up more towers around the US in the first six months of 2010.  This means that I should have already seen improvements in service, and I haven't.  It is being speculated that AT&T's exclusive iPhone contract is coming to an end, and as a result they sent out a letter to customers and held a press conference to publicize improvements to the network as a way to retain customers.  AT&T denies these allegations, saying they simply want customers to know that customer satisfaction is their number one priority. 
Well AT&T I am not exactly satisfied.  I can deal with the occasional dropped calls and loss of service, but what I do have a problem with is not being able to use my phone when I REALLY need it, i.e. game day, Mardi Gras, anytime their are thousands of people in one area and I am trying to find someone.  It also seems that every time I am trying to access the Internet on my iPhone for something I need to find out at that moment, it decides not to work or freeze up.  It is that my expectations for my cell phone are too high?  Does that level of technology in such a small device mean that problems are going to arise?  I have never used another cell phone server, so maybe these are common problems that everyone experiences.  But if not, AT&T may need to spend a few billion more dollars, because I'm sure many people will move to competitors if their iPhone contract really is ending.
