Can you trade an iphone 5 for a galaxy s4 on sprint?

Help please! Also should I keep my iphone 5? I don't know what to do?

Get the Galaxy S4. If you're on a contract with the iPhone 5, you'll have to pay all these cancellation fees ($175-$300 most of the time).It can get pretty expensive and you may end up paying up to $600! But it's worth it. I would do it. I hate iPhones. But if you aren't on a contract with the iPhone 5, then you could trade it in for the galaxy s4

Why would you? Its not a used car lot, I'm not sure why you think they would let you trade like that.
