Apparently the promo is gone and upgrading a phone takes it away. Even if you buy full retail.
That just happened to me.
I purchased my Thunderbolt at full retail and I still have my promotion included. I can't check it right now as their website is down, but I have that along with my 19% plan discount from my job and 20% data discount (which is irrelevant because of the $20 discount). Plus, Verizon even added Friends and Family to my account on a 450 minute plan and that's still active. I guess my point is nothing has changed for me.
Also, that $20 discount was originally stated to be a one year deal. Granted, I was told that it may be extended at the time I signed up, I feel that it's highly unlikely that we'll see that.
