Hello, I saw that I was able to upgrade using the discounted pricing and was interested in a refurbished Motorola Atrix that I could buy for $0.01. I have a Blackberry Curve right now with the 2GB DataPro plan. I saw that the Atrix requires a data plan that is different from the Blackberry plan. If I upgrade and add that plan, will I be charged for both data plans or just the new one? I do not want to upgrade if it means I will be charged 50 dollars for two data plans in one billing cycle.
