As reported from MyDroidWorld, the new update is a leaked OTA update from Verizon, and is only accessible for those who have already rooted their devices. If you need instructions on how to root, visit our previous article here.
There are step-by-step instructions over at their Forums, along with the download links for everything you need to upgrade to Froyo 2.3.13. However, they haven’t posted what the update actually enables, or if it adds any new features for users.
If you have experienced updating in this way, you can head to their forum here for all the information you need. For those of you who are willing to try this out, let us know if it works for you, and any notable changes you have seen on your Droid X.
Thanks in advance!
