Updating first post: Couple of nice improvements have come down in the last day.
Thanks to aatreya, we should have a fix for the weird + dialing issue that has caused Google Voice to fail for so many of you. Add north_am_dialing=1 to your cmdline in startup.txt and it should fix google voice. I'm not sure anyone has tried this yet.
And thanks to bzo, Bluetooth should now be functional. I don't know any of the details on this one.
To enable these two fixes, you'll need the newest
rootfs and the newest
kernel and modules.
I guess I should go test them myself, but... my phone's all the way in the other room.
