In all honesty, you'd be better off selling your Droid, and buying a 8530. With the price difference, you would probably make out with extra pocket money.
Droid's have been selling for $350 or so and 8530's I have seen for $200 to $250 ish...
I have a blackberry tour 9630 if you want to trade. It comes with a spare battery, external battery charger, car charger, zagg invisible shield (with lifetime replacement) and a few apps like bberry weather, tether, berry joosed, and e-gps if you want them.
*edit* (also have a charging dock and all original box items)
