Is there any way I can trade my iPhone 4 in for a for a iPhone 5S or 6?

My iPhone for is 2 years old and I'm currently not in a contract with it (clean esn) and is in really good condition for being a 2 year old iPhone, no cracks or anything. Just light scuffs and not really noticeable scratches on the glass. I really want an iPhone 5S or 6 though, any advice (very strict budget)

Best thing to do is talk to your cell phone provider, and see what they can do for you as far as getting you the phone you want. Just be forewarned, if you are NOT paying for the phone full retail, you will be paying payments over time, and that will be the SAME thing as being on a contract, until the phone is fully paid for.

Then you should also talk to the other local cell phone carriers that have the phones you want, to see what their best deals are.

I would sell my phone and use whatever I got as partial payment on the new phone.
