I love these guys.  They were the first to deliver froyo on the moto droid and from what I can tell by this thread that P3Droid made, this just might be a signed zip that your unrooted and stock Droid X can “apply update.zip”.  Forum followers are all indicating that you need to be stock to apply this.  That means to put back that bloatware and undo any custom hackery you applied for custom notification bars and themes.  Now I should be able to get my wife off my back about getting flash installed on her phone. =D
