not according to the rep I just chatted with; if you have platinum free, you will get the BB option for FREE as well.
I asked that exact question, and was told that..
their servers are getting hammered, so you will have to log in to dish online, click the BB icon on top, register with your online info, and it will give you bb then..
its just going to take them a few hours to bring the server back up, so have some patience!
raymond and matt both told me i would have to let my free platinum go to get it
