I hear that the droid will be getting the 2.1 update soon. I recently just rooted my droid. Will i need to unroot in order to receive the update?
Likley if all you did was root then possibly the 2.1 will cause no problems other than unroot. The 2.0.1 update needed the otacerts file to be intact inorder to update. No one really knows what the 2.1 holds for folks who have phones in different states of "unfactoryness". My suggestion is that if you want to keep root, you do not want to update right away, to see how things shake out. If you don't care about root, I would still suggest not accepting ANY ota's until folks have who may be rooted, to make sure you are not gonna have problems.
And I said any as per a thread in the General Discussion area, some folks are getting updates now that no one is sure exactly what they are. Perhaps a patch for 2.1 that is coming, a maintenance update? The folks that have gotten these report the phone still says 2.0.1, and they cannot see any significant differences. Definately not 2.1. But the exploit "hole" that allowed 2.0.1 to be rooted was officially closed by the Android Development community, so if what is coming out now is something different than the 2.0.1 we got weeks ago, it could have this hole plugged.
Right now, keep track of exactly what you are doing to the phone, and every file, and keep an ear to the ground here.
