Good question, there are a couple of questions and some speculation in the Purism forums about where these first phones have ended up. I would have expected to see a few unboxing videos by now, if they did ship. Most people understand "shipped" has having been handed off to a courier, but maybe the first batch is still waiting to reach a certain number of units before being sent out.

There is a video from someone who says that he is the first backer on Purism's Mastodon channel here: https://social.librem.one/@purism/102875669542336798
