Well we knew that the official Gingerbread update is starting to be rolled out to a small number of lucky Droid X owners, but now the update has been made available for those of you who don't like to wait. Naturally you'll have to be rooted with a recovery from which you can flash the upgrade, so if you're not you'll have wait for Verizon to push the update OTA.
The update is the official Verizon and Motorola approved Android 2.3 upgrade for the original Droid X. The upgrade, as previous leaks have indicated, brings Droid X owners a revamped version of Motoblur, skinned over the 2.3.3 version of Gingerbread (as opposed to 2.3.4 which is currently only on the Nexus phones).
To flash this, as I mentioned before, you'll need to be rooted and have ClockworkMod's Droid X Recovery Bootstrap, so if you've been waiting for the official update because you weren't rooted this isn't for you. If you are rooted, and were just waiting for the official release, head over here and give it a go.
