Which iPad Air WiFi + Cellular carrier will have the best resale value on eBay in one year? As a Macrumors forum user, I know the iPad Air has a single cellular radio globally. However, not all buyers are as savvy. Also, does the Sprint or Verizon model have a better chance of being added by the respective CDMA carrier? I ask because my exchange for a severely yellow tint and the only 128GB was Sprint. I'm a long time AT&T customer, so typically I just get AT&T. Not necessarily happy that I had to settle for Sprint.
