    I got it last night. The only thing I noticed that was different was it broke my N1 Torch app.

    Hopefully it fixes the fact that anything installed on my SD card won’t update unless I move it back.

    I found the right instruction for installing

    1. Download the Android 2.2.1 firmware for the Nexus One Here
    2. Rename the file and copy it to your microSD card via USB. [Note: make sure the file is named and not]
    3. Power down your Nexus One
    4. Hold down the “Volume Down” button as you power the phone back on.
    5. A screen should appear showing your phone’s system searching for various files. Scroll down to “recovery” and press the “Power” button.
    6. When you see the triangle with an exclamation point symbol, press the “Power” and “Volume Up” buttons at the same time.
    7. From the menu that appears, select “Apply”
    8. When the screen displays “Install from sdcard complete” select “reboot system now” and wait for the phone to power back up. (this will take a long time)

    But my update failed when the Verifying process start…
    I see this error on my N1:

    — Installing from sdcard…
    Finding update package…
    Opening update package…
    Verifing update package…
    E:failed to verify whole-file signature
    E:signature verification failed
    Installation aborted.

    Please help me… :-(

      Root is not required for a manual install. If you’re using a custom recovery you will not be able to use the version linked on this site as it is an official update, signed by Google. You will need to head over to the xda forums, and locate the manual install for custom recoveries.

    Just got the update. Right away I got an alert to ‘Activate device administrator’ from my work Exchange server. Also, maybe its my imagination, but all of the home screen icons look a little bigger.

    Just went to do a manual install when it popped up and said there was an update available. Great timing. :)

    Aussie Nexus One.

    But will this update break root, if said root was obtained by something like UniversalAndRoot, and not by unlocking the bootloader and installing a custom ROM?

    My phone downloaded the update but i’ll put off install if it does.

    As for the failed installs, i think you have the Vodafone version of the Nexus.

    Received my auto update yesterday. No problems for me. Only thing I noticed, and this may have come out before, is that while typing the number keyboard will auto appear if you hold your finger on the keyboard and move above the letters. Pretty convenient. Let me know if you discover anything else.

    Just a note to Swype beta users – your Swype will not longer work when you get the update.

    To get it working again do this:

    1. Uninstall Swype.
    2. Run the Install Swype app again.
    3. You’ll have to enter your user/email and password again.

    NB. Probably shouldn’t do it if you deleted the Install Swype app. :p
