Beware of trade in offer
The process for buying a phone is easy. You pay full price for the phone, and they give you a trade offer based on your description of your current phone. Apple makes is easy to return your phone back for a trade in. The problem comes when you receive the email AFTER they have your old phone. They automatically reduce your trade value to a lessor amount. When you decline, they ship your old phone back, but it may arrive in a damaged condition. Now I have my old phone back in a condition that is not worth reselling. Save yourself the time and trouble and just throw your old phone in the trash (after you deletes it contents of course).
