Though sales of the Nexus One aren’t exactly booming, perhaps the addition of the AT&T and Rogers Wireless models of the Android smartphone might give Google a boost. That’s right: available immediately, you can now get a version of the Nexus One that is compatible with AT&T’s and Rogers’ 3G networks (850/1900/2100MHz). Aside from the different 3G bands, the handset looks to be the same as the T-Mobile/unlocked version we reviewed back in January. The Nexus One is available directly from Google for $529 without a contract.
