Confirmed with a Verizon employee the device IMEI has to stay on the same line for 24 months. So no. Sneaky promo.
How is this sneaky? Did you not ask or better yet read what you signed? I like t mobile JOD, just walk in and get a new phone. If you don't want to do that, just pay off the last 6 months and it's yours, all interest free.
