Well, I am getting what I need....
there are a few dead spots for TMO here in Phoenix, but so far it's not been an issue for me. I use my phone for my business, so if I am not reachable, I lose money.
I certainly did like Verizon's coverage better...for instance when I went hunting in SE Arizona, my TMO phone lost signal once I got a good ways from the main I-10 freeway corridor. My friend's VZW phone was still going strong. Since I was hunting and didn't care if I received those calls, it wasn't an issue.
In Phoenix, works fine for me.
Interesting that VZW wouldn't have regional pricing differences to take such things into account.
