Seems like they are becoming more and more common. This weekend alone, I went to a small party where two other people besides me had one and I went to a wedding and was sitting at a table with a guy who had one. Of course, we sat around and compared apps and geeked out. haha.
Call every Sprint, Best Buy, and Radio Shack store in your area. Keep checking sprint.com. Get on every waiting list. Eventually someone will have one.
