Iphone trade for a better iphone?

I have a galaxy s4, which i'm trading this girl for a used iphone 4 and extra cash. Would verizon let me trade a iphone 4 & extra cash for an iphone five? If not this way and you know more ways to trade please let me know.

Yeah. The amount of cash you're going to need will vary depending on if you have an upgrade or qualify for early Edge. You're always better off selling the iPhone yourself though. You'll get more money than Verizon will give you.
