I traded mine in on 9/18 at an AT&T Corporate store and have yet to see the credits. From an earlier thread, it sounds like some people started seeing the credits a couple of weeks ago. I don't have a good feel for what percentage of the people have received theirs, so I don't know if I should be alarmed yet or not. I had assumed that since I traded my phone directly at the store 2 days after launch day that I would be one of the first to receive credit, but maybe it doesn't work that way.
