I was wondering if I replace my dead VIP722K with an eBay refurbished unit, can it be authorized on my DISH account? I do not want to upgrade. Would I take my smart card out of my unit and put it in the new unit or will the smart card in the refurbished unit work? I've received conflicting information on this. Will there come a time when DISH will no longer replace my VIP722K unit and force me to upgrade? They've already told me that the VIP722K is obsolete. Thanks for any information.
