How much would I get for my iphone 4S?

The only downside about the phone is that it has a bad ESN. I'm guessing that means it is lock on Sprint(?). Other than that it is a white 16GB iphone 4S. Are there any stores or websites that let your trade in your phone? Other than T-mobile trade your iphone 4s for a iphone 5 plan.

Hello there have you tried CEX stores they specialise in trading devices for others or they will right out buy the device from you.

Check out the link address and see what you can get from the them.
