It was just a link to an unlocked AT&T N1, they are all over ebay, but people are selling them used for more than what they were new. It's just cause you can't buy them anymore from Google without being a developer.
Not sure what network you want to be on, but T-Mobile is coming out with the G2 which looks like it will be a pretty sweet phone. It's very N1 like, has a keyboard but is very thin, and the first HSPA+ phone.
