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

From 2.2 FRF85B to 2.2 FRF91

From 2.1 to FRF50

From FRF50 to FRF72

From FRF50 to FRF83

From FRF72 to FRF83

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.

maybe less than 4-5 minutes for the whole thing.

I have a total of 275 M of free memory according to Taskiller O_O!!!!

I'm install adobe flash 10.1 beta from market place now.

Doesnt look like any applications can be move to SD card atm.... :(

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.

doesnt work for me i get error E:Can't open /cache/recovery/command

*edit apparently this update doesnt work for the ATT/Rogers model

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

From XDA :

I have the AT&T version of the Nexus one, and it worked perfectly for me! I ADB installed EFE27 then Froyo, and everything is working...

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!

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)

this is what happens when i click the trackball
