    Here's a thorough run through of everything that FroYo brings:

    Android 2.2 Froyo: everything you ever wanted to know -- Engadget

    Unfortunately, for now, this method is only for stock users of the "T-Mobile" version of the N1. If you are rooted and have an unlocked bootloader, I have special instructions below.

    There're are a few ways to end up at FRF83. If you're on 2.1, go to FRF50, then straight to FRF83.

    If you've already flashed 50, then 72, take the file from 72 to 83.

    Manual Update Instructions

    1. Download file from the following link(s):

    From 2.1 EPE54B to 2.2 FRF85B

    http://android.clients.google.com/packages/passion/signed-passion-FRF85B-from-EPE54B.75b107d6.zip

    From 2.2 FRF85B to 2.2 FRF91

    From 2.1 to FRF50

    From FRF50 to FRF72

    https://android.clients.google.com/packages/passion/signed-passion-FRF72-from-FRF50.bc033f9e.zip

    From FRF50 to FRF83

    http://android.clients.google.com/packages/passion/signed-passion-FRF83-from-FRF50.38d66b26.zip

    From FRF72 to FRF83
    http://android.clients.google.com/packages/passion/signed-passion-FRF83-from-FRF72.684bd56a.zip

    If you don't know your build number, go to settings, about phone

    2. Rename the file to update.zip

    3. Note that if you're using Windows and don't have "show file extensions" turned on in the file explorer you won't see a .zip. Just rename it to "update" (no quotes, of course) because it's already a zipped file.

    4. Copy the update.zip file onto the root of your microSD card (that means not in any folders)

    5. With your Nexus One off, hold down the trackball and press the power button.

    6. You'll be booted into a white screen with three Android robots on skateboards. Select "Bootloader."

    7. On the next screen, select "Recovery."

    8. Your phone will reboot, giving you a picture of the Android robot and an exclamation point inside a triangle.

    9. Now press the power button and volume up button at the same time. It could take a couple of tries.

    10. Now (using the trackball this time) choose "Apply sdcard:update.zip" and let things run their course.

    You can get this update, which has been prerooted for you by Paul @ MoDaCo. You know the drill on how to install these ROMs:

    UPDATE: Froyo has been rooted! - *This may now be outdated.

    My understanding about the Apps2SD support is that devs have to enable it. There is increased piracy risk, so Google didn't want to force it on them. But I feel it's going to become expected for devs to enable this fairly quickly.

    Supposedly it will work w/ATT model. You have to install EFE27 first though...

    From XDA :

    Or just wait for the AT&T version which will probably appear on Google's servers soon enough.

    I thought that at first too. Turns out you need to press the trackball on that step and not the power button and it worked for me despite seeing that message.

    I am now succesfully running 2.2. But I ordered the N1 direct from google with no carrier (I am in UK)

    Alright, I've merged the two threads on how to do this, updated my guide, and stickied this thread!

    You lucky N1 owners enjoy your FroYo goodness!

    I merged the threads. Mine was posted first, though just barely :D

    But thanks for your post also! Saved me a lot of work, having to dig up my guide for the 2.1-update1 :p

    i got that E: Can't open/cache/recovery/command error..

    Didn't matter. I was still able to update it! After it installed it.. didn't have to hit reboot or anything. It did it all by it self. :D :D

    Got Froyo 2.2 running now!

    2.2 has some nice updates. There is finally an option to recognise swearing on voice to text.

    Yes! Just updated my UK phone, worked a treat, although my calendar apps no longer work. Pure calendar widget, pure grid calendar and calendar pad. Main calendar app works fine. Phone much snappier now and little tweaks keep showing up. Excellent.

    I've added this to the original post, but 2.2 has been rooted! Thanks to Cyanogen (no surprise here)

    Instructions to root 2.2 are in the first post now, as well. Enjoy!

    In case you don't know, root access will allow you to do things such as take screenshots w/ drocap2, remove system apps you don't use, flash a custom recovery, etc...
