Google is also celebrating today - Android 2.2 Froyo has reached two important milestones. Google open sourced the latest version and they are pushing out the final Froyo update to Nexus One users. And we're sure the timing has nothing to do with the launch of the iPhone 4.
Sure, Froyo has been available to Nexus One users for a while (mostly on dev phones and through manual updates), but this seems to be the final, official version of Android 2.2. You could manually download the update from here (it works only if you're running FRF50 firmware), though if you don't know what you're doing, you should wait for the OTA update.
Your Nexus One should automatically check for updates or you could force a check (go to Settings -> About phone -> System updates), so one way or another you should be getting a notification that a new version is available and download it Over-the-Air.
Some people are reporting that the update is not available for them yet, so it might not work right away - rolling out updates is a gradual process and it varies by location too.
The other important milestone for Android 2.2 Froyo is that Google open-sourced the code to their partners and manufacturers and everyone else too. This means that they can start working on Froyo firmwares for the non-Google phones.

I gotten an update this morning on my Nexus One via OTA even though I had installed manually for Froyo 2.2 build number FRF83. Now my build number is FRF91. Anyone gotten the latest?!!
