Trade in iPhone 5c for iPhone 5 with AT&T?

I have an iPhone 5c but I actually want an iPhone 5. I just got it back in October. Would I be able to do this without being charged?

The iPhone 5c is the SAME THING as the iPhone 5… The 5c just has a plastic cover… (And the 5c has a better camera than the 5 I think)

Anyway, I hope you know that they discontinued the iPhone 5. You can only get the iPhone 5 used.

But you CAN get the iPhone 5s new. But they will charge you. Also I don't think they will take back the 5c, but they might, you could try anyways.
