What happens if purchase it at BB using an available upgrade on a family plan and ESN swap it to another line on the same plan?
When I bought my Pre I jumbled a few lines to get it and BB took care or everything.
When I bought a Pixi they said they could not do what I wanted, buy but activate on a different line, I had to do all the work when I got home. I'm gonna try to get BB to do the whole thing and have a back-up if they won't.
just a note: from what I understand if you buy from sprint, posted on their facebook, and do an ESN swap to another line you are not eligible for the rebate. It has to stay on the original line for a certain time.
