Plan change going from a 3g phone to a 4g phone?

I've got a D2 that is starting to crap out on me, and my g/f is giving me her Droid charge until my Upgrade is up early next year. My question is am i going to have to change my plan if I go from 3g Droid 2 to this 4G enabled Charge. Especially since i have the Unlimited data plan I'm still rocking.

No, there won't be any change in your data plan, you are grandfathered in for the time being.
