At first glance there doesn’t appear to be any difference between this thing and the Droid 2 that you can buy today, but the differences are subtle. The only obvious internal change is that it can be used globally. Droid Life claims that this is the Droid 2 World Edition.
It sports a pearly white back and a lighter chrome bezel in front. It might replace the original Droid 2 completely, but until we see some official information no one knows for sure. The OMAP3630 core is apparently clocked up to 1.2GHz. The plain old Droid 2 does 1GHz.
