Is unroot necessary or is just 2.0.1 enough?
Are you asking how to get the 2.0.1 update over the air? Your phone will have a popup that ask if you want to update. If you are asking about the 2.1 OTA update, it is not officially available for the Droid yet.
the way that i understand it is, as long as you haven't messed with the OTA blocker, you will be presented with the update. however, what that does to rooted phones is yet to be seen.
it may just wipe out root and you'll have to start over. you need to monitor the progress of what people are doing about the OTA before you decide to move forward with it.
this is true with anything you do that is outside normal operations (like if you hack a video game console).
I am wondering when I will get 2.1 on my droid. I am hearing 1/22, then end of month, then a pre-update update before I get the 2.1. Does anybody have the right info? And why is it that VZ customer service is the last people to know anything about it?
