I came from a Media Works plan that I'd been grandfathered with forever. When I got the Captivate, they made me change it. The store rep was unable to change me back to Media Works. So I have a ticket in for the AT&T 611 folks to change it back. When I physically brought it back, I unrooted it, formatted everything, and returned it as close to stock as I possibly could. The rep never even turned it on. He took out the battery to make sure the IMEI matched the one on the box, and that was it. Granted I assume they could look into it after I left the store, but who knows. Just thought I'd post in case others are wondering how difficult it would be to return one when/before the 30 days is up.
