ATT next trade-in condition?

Added (1). I'm on AT&T Next and wanted to upgrade from my iPhone 5c. My 5c was broken, and I paid $99 to replace it, in order to upgrade. AT&T told me that if I did this, I could pay off my remaining balance and get my new phone. When I took my insurance phone in to upgrade, they told me I would have to wait a month to get a new one. Over the past month, I got a small dent in the top of the top of my phone. Will they still accept it for upgrade? The dent is very small, otherwise the phone is perfect.

They probably will not accept it. It has to be in "certified like new" condition. Best bet, just go in to a staore and ask ahead of time, then you will know your options.
