My gf and I both upgraded to the Droid 2 Global, I got the Blue and she got the White. I already had the Blue extended battery from my time with my original Droid 1, so that was a no biggie. I was able to order the R2D2 Extended Battery from the verizon wireless website, and it really is a pearl white with the simple black Motorola logo on it, matching the original flat battery door cover.
I had a store representative who wasn't that bright, didn't even realize that the R2D2 was a Droid 2, let alone had the same battery as the Droid 2 Global so I had to explain a lot to her. The store had no "white" cover extended batteries (BP7X), so I had to order it online.
It fits perfectly into the official case she bought when we got the phones. Mine fits my Body Glove Droid 2 Case perfectly as well.
