Since the 'no further support' thread is no longer applicable, i'd like to direct community attention to what we can do to continue development on the 770, and that is testing, bugreports and development of ITOS 2007. See these threads.

Some hope for 770 owners...
Nokia 770 Development to Continue

And especially,
OS 2007 on 770 mk2 now available

The garage page is here:

The wiki is here:

In particular, my last issue with Os2006 appears to have been addressed in 2007:

"If new Xomap [Hardware scaling on Os2007] doesn't work on the 770, I'd like to know about it. (I don't have time to constantly test it, but I can -- and will -- fix it.)" - Daniel Stone

Does he rock, or what?

So clearly, it2007 is where we can do something productive to keep improvements and bugfixes coming to the 770. I've currently flashed my device to it, and am working to resolve or file bug reports against issues I find.

Cheers
