The quality of your service is 100% rooted in where you live and where you are at that moment. Everything else is absolutely meaningless.
My iP4 is on Verizon, and the service is good, but the company is awful. Their billing practices are criminal.
AT&T sucks, and hasn't a prayer of getting a dime of my money ever. I lump them in with Chase bank and Comcast...meaning satan's trifecta. Ma Bell should be starved, and never fed.
I'm looking forward to consolidating...
