I would concur with this assessment.
My AT&T experience has made me realize why people throw their phones.
I have never had such frustrating service before. I am currently considering just cancelling my cell phone service all together as horrible as the experience has been.
I think in our area they have just oversold the network and there is simply no room so good luck trying to place or recieve a call.
Ironically text seems to work ok. But if I wanted to text all day I would have gotten a moblie card and used my laptop.
