This is a new system and kernel, you will be able restore a nand backup to (4.5.588 or 4.5.573) but you can not restore back to Froyo.
This will install right over the top of any previous Gingerbread installs. I have not tested this against other offshoot roms (Apex, Liberty, etc.) You should install over those at your own risk. If previous GB build has been Modified or Themed you will need to return it to an unmodified state.
I have not added any easter eggs or other mods to this release, the only change made was to the build prop to fix the Market Applications not showing.
If you find that your phone is no longer rooted after installing this Firmware, you should use Gingerbreak to re-reoot your device.
Dowload the zip
Reboot phone into Clockwork Recovery
