I bought one at an ATT store, and they started asking for e-mail and such.... and I just told them no, I would not give it to them. They said fine and sold it to me anyway. ATT just needs to be told who is boss. You don't want to give them any info, don't. It is NOT required for purchase.
If you want to buy a whole bunch, get one of those one-use redit cards, I know AMEX has them. Buy a few phones, get a new card number, buy some more.
I swear, these Gestapo tactics from both "A" companies is a bit much. They need to remember, they are service providers, and we are the customers. Without us, they go away. They could really learn a few lessons from companies with good customer service- like Disney or AMEX. When you want something from Disney, they figger out how to do it for you, and get it done, not restrict you or shoot you down. Remember when Apple knocked two bills off the iPhone price? It was AMEX who first- and with no questions- made that good to customers. Apple only did it when forced to by public opinion. Apple may design a good product, but they suck at CS.... and even then they are miles ahead of ATT!
