The Nexus One was released today! Built by HTC, the unlocked version is $530 (the phone works with “nearly all” GSM SIM cards, according to Google) or you can pay $180 for the typical two-year contract with T-Mobile. if you already have tmob service, but don’t have a data plan, it will cost $280 for the phone. Google says there will be other carriers and plans coming sometime in the future. I think the arrival of the Google phone pretty much spells the end for the Droid.
