I'm sure it will; it will, however, most certainly not say "You're running the N800-Version on a 770, which is something we never supported. We now it worked until now, but the new version will set your batteries on fire if you install it on the 770. Are you really sure you want to proceed?"

The point is that even when I'm asked if I want to upgrade, I will not know if it's safe. It's simply strange to have the two versions without knowing why there are 2 versions.
