I have a PPC6700 for about 3 years now and its starting to show its wear. I filled out the replacement form online and qualified for a Touch Pro. When I got my confirmation email, I noticed it said I have to send in my old phone or get hit with the fee. So I emailed customer service asking if I can keep my current phone as a backup (this is my 1st and only sprint phone) and they said I can keep the phone without any fees
