Currently I have the Droid 3 with unlimited data, and obviously now my upgrade isn't available until 2013. However, I can switch my parents upgrade to my line. If I do this, will I still keep my unlimited? It's not my upgrade really.. kinda, so is that still grandfathered in? Asking this because I'm definitely likely to get the Samsung Nexus(Droid) Prime.. especially if the rumor is true that it will come with a Quad-Core processor(assuming battery doesn't suck).
