I recently received my second Google/HTC Nexus One. The first one I bought on eBay, and was not 3G compatible with Canadian carriers. But it was one of the first ones sold in the US when they became available in January of 2010.
I couldn’t have timed the purchase of my second Nexus One better. I ordered it on July 20th, on July 21st Google discontinued direct online phone sales, and I received it on July 22nd.
The Nexus One is now available unlocked to registered developers only on the Android Market. But it appears to be only the version with the radio tuned to the carrier frequencies used in the US for 3G, the same unit as my earlier model.
Here are un-boxing photos of my second Nexus One and the car dock.
