I am so glad someone finally went public about this issue! I am also a long term ATT customer, maybe not 12 years but I have been a customer for 8 years. I went to the local ATT store in Brea to upgrade my blackberry to the new iphone. When I got there, I was told that they were out of stock and i'd need to place a "special order". Instead of doing that I decided to go wait at the mall...even though I had to sit and wait for a couple of hours. While waiting at the mall I decided to call the same ATT store back and see if they had received any more deliveries. Over the phone I was asked "Do you currently have ATT?" So I said "No, I have T mobile". Not only did the rep offer to HOLD and iphone for me, but they reminded me not to forget a copy of my Tmobile bill!!!! I will never shop at an ATT store again, from here on out I will just go to Apple. Plus the people at Apple are MUCH friendlier.
