Sell it to a pawn shop, or one of the machines in malls that take phones youwill get more for your device
I am not sure about you have to ask them I never went to the phone part
Sell it on ebay
Best buy have a trade in service that you get in store credit from best buy and use it in best buy.
I don't think you'll get credit from them for that. Only if they have some special Exchange program. You're better off selling it on your own and then going and buying a new phone
You will need to go to the store and ask them.
