This is an interesting bit of info. Apparently, there are some users out there that have received an OTA update on their Droid X2, including one user that received a replacement Droid X2 with the update pre-installed. The version is 1.3.418. Motorola had previously announced a soak test for the device, and that it would be coming soon. Oddly, there has been no indication that this is that update. In fact, Verizon’s support document still says that the update is "coming soon." Sound off in the thread if you are one of the folks that have received this. Everyone else... feel free to share your theory as to the origins of this phantom update.
