If I buy a used iPhone from GameStop, is it possible to switch my Sprint plan to it?

I'm wondering if I bought one from a local GameStop, can I switch my current phone (which isn't a smartphone) to the iPhone on my Sprint plan if I bought a data plan to go with it.

Friend, i worry it can't switch your Sprint plan to it, maybe you could ask the service, and i think you could go to MoonarStore have a look, there have the phone that could swith the item you mentioned, hope this could help you, good luck
