Exclusive: Nexus One full specs detailed, invite-only retail sales starting January 5th?

We know you're itching to get your hands on a Nexus One -- Google's managed to build buzz here the way only a couple companies in the world know how. Unfortunately, it sounds like you're going to need to cross your fingers (or pull out that eBay emergency stash) to get one out of the gate, because we've got some intel here suggesting that it'll be available only by "invitation" at first. Our tipster doesn't have information on how those invites are going to be determined, other than the fact that it's Google doing the inviting -- if we had to guess, current registered developers are a strong possibility -- but the good news, we suppose, is that T-Mobile will apparently sell the phone directly at some to-be-determined point in the future. Oh, but that's not all -- we've got specs, too. Lots of them. Here are the highlights, but follow the break for the whole shebang:

  • Android 2.1

  • 11.5mm thick

  • 512MB RAM, 512MB ROM, 4GB microSD in-box expandable to 32GB

  • 5 megapixel camera with mechanical AF and LED flash

  • HSPA 900 / 1700 / 2100, 7.2Mbps down and 2Mbps up -- in other words, yes to T-Mobile 3G and no to AT&T 3G, though you'll still be fine on EDGE

  • 3.7-inch WVGA AMOLED display
