We've been dialing a lot of things in on the motherboard. The biggest noticeable change is the GUI. It looks much more polished now. We're almost ready to start carrying the phone around for daily use.
Other changes are:
- fixed some noise issues in the audio circuit. (BTW, wideband audio sounds much better than the older generation of VoIP codecs)
- lots of software improvements. bug fixes, added messaging, boot screen, main screen, NTP based clock, and an expandable menu system
