I'm all in favor of the iPhones having AT&T's network. I don't have an iPhone and won't be getting one, and my phone has already been bumped off with 'Network Congestion' way too many times in the past few months.
Since AT&T's taken on the iPhone, there has been no network upgrade/expansion in the area I live. My basic phone service is as tempermental and annoying now as it was 5 years ago when I moved into this place. Even the 'upgrade plan' map that the salesperson gave me the last time I changed up phones is identical to the one I was given 5 years ago--just with the years changed to reflect the passing of the years.
After being with AT&T for over 10 years, I'll be changing to a carrier that does provide service to my home when I need to change phones next. Nothing AT&T can say will change that...they've had their chance these past 5 years.
Always draw your curves, then plot your reading.
