FedEx just dropped off my gold 64gb Verizon 5s, but second-guessing myself whether to keep it or just use my Black 64gb 5. I heard that if I return it to VZW, I'd probably get hit by a restocking fee even if I bought it full-price to maintain my unlimited plan so I was thinking of selling it (note not profiting from it) .. does anyone know if the phone is already linked to my phone number and the SIM card in it (if any as I still have the iPhone 5 sim) is also tied to my account? Could anyone weigh in if my account/phone no. might get compromised if I decide to sell it sealed in box? Thanks.
