Looks like Google is finally ready to be serious with the Nexus One. As of today, the device is fully compatible with AT&T 3G, as well as Canada’s Rogers Wireless 3G bands. Previously, you could use the Nexus One with those carriers, but you wouldn’t be able to get 3G speeds, so you were relegated to the much slower EDGE network. You can purchase the new model, which is the same as the upcoming Verizon and currently available T-Mobile Nexus One units in every other way, as an unlocked device without a service plan, directly from Google for $529.
