Hey Scott,
I cooked up a 21015 yesterday and this thing is solid. I didn't see much in appreciable speed difference from rev B, but heck, they are both solid, stable and awesome.
I am curious if anyone has had an issue with UC. I keep the file mostly the same and just put a colon in front of the apps that are already cooked in so they don't attempt a re-install. With this latest build, the UC aborted when the file wasn't in the specified location. My process, which may help out some folks new to UC is this:
Flash - w/o SD card
Hard Reset - w/o SD card
Once the reset is complete, I compare my SDConfig.txt with what is installed on the phone already
modify SDConfig to install my remaining apps
Hard Reset - WITH the SD config
I find that a consistent process helps to isolate issues
Love the Kitchen, the ROMS and fellowship. Life is GOOD!
