Gizmodo has uncovered details of the upcoming Google designed handset  Some of the more interesting tidbits include:

• Unsubsidized: $530
• Subsidized: 2 year mandatory contract and $180 for the phone
• Currently 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
• Want to keep your plan?  You have to buy the $530 unlocked version
• 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
• Google will still call it the Nexus One apparently, and not the Google Phone

• 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.

One weirdness in the Terms of Sale that we quickly glanced through was that Google made sure you acknowledged that the manufacturer is HTC, and not Google.
