Update Droid to 2.2 over wifi possible? I have a Motorola Droid running 2.1 that does not have Verizon service.  Therefore it does not seem to be getting the over-the-air (OTA) update.  Is there anyway to update this via wifi?
You can manually update your phone by downloading the update.zip file for 2.2, putting it in the root of your SD card and applying the update in the recovery during boot up.
