Nexus One Getting Froyo 2.2.1 Update Via OTA And Manual Update

Nexus One Getting Froyo 2.2.1 Update #froyo221 http://snapvoip.blogspot.com/
With All the updates abound, Google has decided to update their own Android, Nexus One. Accordint to the information on XDA forum, no one clearly know what this exactly mean but it seems Androot exploit is patched. There also seem to be improvements in WiFi operations.
Here are some basic information from the forum;

    * Android version: 2.2.1 (!!!!)
    * Baseband version: 32.36.00.28U_4.06.00.12_7
    * Kernel version: 2.6.32.9-27240-gbca5320
    * Android-build@apa26 #1
    * Build number: frg83

 The official release is available to download from Google Android Site (http://android.clients.google.com/packages/passion/signed-passion-FRG83-from-FRF91.c8847c98.zip)

But as with the Android community's capabilities, there were instructions and modified ROM available to download.
The senior member Devastatin tells us how to do a manual update, on an Unrooted normal (but unlocked) Nexus One;

1. Download the Android 2.2.1 firmware for the Nexus One.
2. Rename the file update.zip and copy it to your microSD card via USB. [Note: make sure the file is named update.zip and not update.zip.zip.]
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 sdcard:update.zip.”
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)
