This update leaked to the web a few days early on Motorola's site and it looks like it was pulled until tomorrow (12-12-06) for the launch of the Black Q. I'm curious about the version number - obviously a hex number, but I'm curious if 06.0B.0B references the build date or a reference to black. If it is a build date, it would mean 11-11-2006.
Anyway, you can catch the discussion about the new release
here.
If you happen to read this post tonight, there are plenty of secondary links from that site that host the new build, or you can wait until tomorrow.
Other people have noted that the overall speed of the phone has improved and that the Bluetooth serial port is working properly again, which was apparently broken in the older build.
