It is a sanyo scp-6780 pretty nice as oppose to my candy bar cell phone. This has a sprint service. Now here is the kicker, I tried calling all the contact to return the phone and finally reached the daughter of the owner. She is an adult and she told me to wait while she tried to reach her mom the owner. Then she calls back one hour later and she told me to keep it. WTF? I told her to give me her address so I can mail it to her. She said just keep it and will get another one. What do I do with this now?
