How to upgrade to Android Froyo

I have just installed Froyo on my Nexus One. Official OTA update is not available yet, so I had to install it manually. Best explanation how to do is described on pocketnow.com (http://pocketnow.com/tweaks-hacks/video-flashing-froyo-on-your-nexus-one), here are the steps you should follow:

For those of you who want to run Froyo on your Nexus One, and have not flashed a custom ROM:
1. download the Froyo image
2. rename it to update.zip
3. copy it to the root of your sdcard
4. reboot into recovery mode
5. flash the update.zip file
6. enjoy your Froyo

If you're running a custom ROM and want to run Froyo, you'll need to:
1. backup (optional)
2. wipe
3. flash the stock ROM
4. flash the stock recovery.img
5. get the 2.1 Update 1 update OTA (see video)
6. go through the previous steps above for non-custom ROMs

After using Froyo for a while you certenly will discover that system is a bit faster. Sliding between home screens is smoother and browser works a lot faster. Other applications also seems to open quicker. More about the update you can read here: http://googlesystem.blogspot.com/2010/05/android-22-froyo-is-major-update.html
