Big thanks to the folks over at this XDA thread that discovered the URL!

What You'll Need To Flash This
- At this point, Nexus One with the stock recovery and system image. Looking at the title, I'm guessing you'll need to be on ERE27
How To Flash
I grabbed these instructions from Android Central, so be sure to show them some love:
- Download the update from here.
- Rename the file to update.zip. Note that if you're using Windows, just rename it to "update" (no quotes, of course) because it's already a zipped file.
- Copy the update.zip file onto your microSD card.
- With your Nexus One off, hold down the trackball and press the power button.
- You'll be booted into a white screen with three Android robots on skateboards. Select "Bootloader."
- On the next screen, select "Recovery."
- Your phone will reboot, giving you a picture of the Android robot and an exclamation point inside a triangle.
- Now press the power button and volume up button at the same time. It could take a couple of tries.
- Now (using the trackball this time) choose "Apply sdcard:update.zip" and let things run their course.
Ways To Root
The two biggest players in the Nexus One rom scene have already rooted the rom! You have two options:
- If you're coming from stock and want to root, then follow steps above and then apply this update from Cyanogen.
- Or, if you're coming from an already rooted rom/recovery, just apply this update from Paul O'Brien
I haven't tested either yet, but will as soon as I get home (in an hour or so). Drop us a line if you've used either method.
What About AT&T Nexus Ones?
Users on unrooted AT&T Nexus One's will have trouble with the above steps since the rom is designed for coming from the ERE27 version of 2.1 which is T-Mobile specific. However, it seems that if your AT&T Nexus One has been rooted, you can flash the update using a third party recovery image and still have 3G. Here is a user report from XDA-Developers:
Installed Paul's Update using Amon_RA custom recovery on an AT&T. Confirmed that I have 3G coverage and everything seems to be in working order.
Anyone brave enough to try these steps? Be sure to drop us a line if this works for you. I'll update this post as more information becomes available.
