Will Apple still want my broken iPhone 5 since they are sending me a new one?

I called Apple support yesterday and I told them my screen had cracked on the iPhone 5 and they told me they couldn't repair it cause its still so new so they will charge me $250-$300 which I have no problem paying. I'm wondering though will they want me to send my broken iPhone 5 to them after they ship me a new one? Cause I wanna sell my old one to get the money for the new replacement. Does anyone know if Apple will force me to or not?

If they are sending a replacement for free they might want to see the old one. If you are buying the replacement out of your own pocket you shouldn't have to send back the old one.

None of this makes sense by the way.

They should send you a new one for free if it was broken thirty days or less after you bought it. This doesn't make any sense at all.

Could go either way
