Looks like this cat's really out of the bag now. A trio of videos of the Motorola Opus One surfaced on YouTube, spied by IntoMobile and subsequently were pulled -- a telltale sign if we've ever seen one. It's now confirmed that it's headed for Sprint's Nextel arm (which we suspected) and possibly Boost Mobile, that it's running Android 1.5 and goes by the "p1_opusone" code name. The folks and Android and Me snagged some screen shots, which is what you see above.
So, it looks like you folks on Nextel should have a solid Android option coming relatively soon.
