I'm using my Thunderbolt right now which is fine. I have a Droid 2 Global that I was using before this, but it's been on the shelf since. With the recent gingerbread leak for the D2G, I installed it on that phone and would like to use it for a change just to get a different feel. I have unlimited data since I've had the thunderbolt well before the tiered data plans came into effect, but I'm just wondering... will I keep my unlimited data if I downgrade from a 4g to a 3g phone? I'm almost positive I should be okay, but that small doubt in my mind holds me back. Just wondering if anyone has a better idea and could help me out. Thanks!
