File this under "Don't know ... Could be ... Who knows ... Take with a grain of salt ... Maybe ..." and any other number of qualifiers, but the Boy Genius Report says it's heard that there may be a second unlocked version of the Nexus One, and that it would sport support for AT&T's 3G (that's the 850 and 1900 MHz bands, if you're playing at home). That's it for now. Could just be rampant speculation, could be more. We'll find out something in three days.
