Can I still trade in a cracked iPhone 4s for an iPhone 5s/5c?

It's okay if I have to pay some money, it's better than having to buy a whole new phone and get a new contract and stuff. A little while ago my phone got ran over by a car and it still worked, but then we got it fixed. I guess it was still delicate though, because it cracked a little bit again. Ever since the car thing it's been really laggy and slow, it's really annoying. So yeah, can I still trade it in?

You might be able to trade it in but for a low discount, the quality of the device doesn't really matter when trading it in but to be honest its not going to give you a very large discount
