I do think(hope?) that in time there will be at least one truly open source solution for the 770's Operating System(nothing iPhone-ish, though) While I don't expect Nokia necessarily to give the community total freedom in developing the OS further, I can't see how it'd hurt them to open it up quite a bit more than it is right now.

I also have these crazy dreams that sooner or later someone with an approximate ton-load of coding knowledge will take an interest to break open just exactly what it is that needs to be done to work out an entirely new system for the 770.
