One of our members just received his Google I/O attendee Droid in the mail. Unfortunately, it arrived with the Nexus One instructions. He posted about it on our discussion forum here:
If you have the proper instructions for the Droid and could provide them to him, I'm sure he would appreciate it. Best way to do that is either posting it directly to discussion forum topic linked to above or you can contact him directly via meetup member-to-member email support on the site. If you do post the information on the forum, that will be helpful in the event the same thing happens to any other group members attending Google I/O this year.
