Will changing my plan erase my new every two discount for verizon?

My phone broke, so my friend gave me a blackberry phone to use, which means i need to change my plan so it is blackberry usable. My new every two discount is available in december. does that mean if i change my plan to the blackberry capable plan, that my new every two will be ruined?Will changing my plan erase my new every two discount for verizon?Nope with verizon you can change your plan as much as you want %26amp; they dont extend your contract for doing it. You will still get your upgrade in December.
