Advertisements Some time ago (a year? two?) there was a sale. An 'upgrade' offer, to move a lifetime service to a new Bolt. The requirement was that the TiVo to be 'traded in' had to have been used in the past 12 months. Yesterday, I plugged in my stack of old TiVos to phone home and update the program guide, even though they are not carded. I am curious now, is there some way of checking/confirming the last sign-in date for these TiVos? These are 4 old ones, but all with lifetime, and I imagine there's some value to keeping them around?
