if you need to get around the activation screen when flashing a new rom; ex. you don't want to program your phone with verizon. there is a very simple way. Not sure if anyone has seen this.
but when your phone first comes on and there is the little picture of the droid bot and the hand showing you to click to begin setup. DO NOT click the droid, instead touch the four corners of the black background (not the corners of the phone) clockwise 2 or 3 times.
thought it may help someone.
