This is the official file direct from Google's servers so you can either wait for it to come to you or go ahead and install now. Please note that this version is only for those that are on stock Android 2.1 right now so if you are rooted and on another rom you should wait for whatever you are running to be updated or get back to stock before updating.

To manually install Android 2.2 on the Verizon Droid, perform the following steps:

- Use the d-pad to navigate to "apply sdcard:update.zip" and select it.
