Yes, but you would get a lot more selling it online.
Yes that do but if the phone works you can get about a hundred bucks for it if the phone doesn't work it's pretty much nothing if it's a model that's only a year old you can get two- three hundred bucks
As far as I know they don't. And I'm pretty sure.
Do an Internet search for possible purchasers. Usually best to keep the old one for emergencies. At Best Buy you can occasionally find discontinued phones which are cheap and perfectly good.
Doubt it. If they do, you won't get much for it
