My situation: Old iPhone 3S, I switched carriers months ago, so no active AT&T contract.
I used the AT&T Wireless Support Chat, Tech Support. Told them I wanted an unlock. Initially got told they couldn't do it, I quoted the press release article. After a couple minutes, the tech opened a ticket for unlocking and said I'll hear by April 16th, 2012. So we'll wait and see.
Short version: Chat works, but be ready with that copy and paste. Also reading asking for a supervisor is helping some folks.
