Gizmodo was tipped with several screen shots of what appears to be the official Nexus One landing page and pricing for the phone. You're given two options to get the Nexus One upon release: Sold directly from Google. Unlocked and unsubsidized for $530. Or $180 if you're eligible and sign a 2-year contract with T-Mobile. In addition, here are some new details copied from Gizmodo:
• If you want it subsidized, you'll have to sign up for a 2 year mandatory contract
• There's only one rate plan: $39.99 Even More + Text + Web for $79.99 total
• Existing customers cannot keep their plan if they want a subsidized phone; they have to change to the one plan, and this only applies to accounts with one single line
• If that doesn't fly with you, you have to buy the $530 unlocked version—this actually might save you money over two years if you already have a cheap plan
• Family plans, Flexpay, SmartAccess and KidConnect subscribers must buy the phone unlocked and unsubsidized for $530
• You can only buy five Nexus One phones per Google account
• There is language in the agreement of shipping outside the US
• Google will sell it at google.com/phone, which explains what they were doing with that page a few weeks ago
• Google will still call it the Nexus One apparently, and not the Google Phone
And here is a big one:
• If you cancel your plan before 120 days, you have to pay the subsidy difference between what you paid and the unsubsidized price, so $350 in this case. Or you can return the phone to Google. You also authorize them to charge this directly to your credit card.
UPDATE: Engadget got the full terms of sale.
