Looks like the Nexus One news train will continue yet again this morning, though this time it’s less imagery, more substance. Engadget has managed to score some very detailed spec sheets courtesy of a well informed tipster. The good news is that every little detail of the phone seems to be available here, so if you were wondering if the Nexus One had a “tricolor charging and notification indicator LED” then you’re in luck. Some not-so-exciting news is something that sounds worse than it really is.  According to Engadget‘s tipster, January 5^th remains the for sale date, but only to “invitation” only folks. That’s pretty vague info, as Engadget, like ourselves, have no idea who or what will determine who receives “invites” to purchase the device. The better news is that T-Mobile is, as we have guessed previously, going to sell the phone directly at a “soon-to-be-determined” point in the future. For the moment, the “invites” and T-Mobile direct sales are still up in the air info so we’ll continue the waiting game to find out what’s really what for getting this device in the hands of the T-Mobile faithful.

Hit the jump for the rest of the specs!
