I had a weird upgrade experience. The ROM image downloaded fine, then it said, "Updateing phone" and just went on like that forever. So I gave up and unplugged the phone anyways.

IT STILL WORKED!! I guess once the ROM image is in you're probably ok.

On the changes/improvements -
The registry is way more organized and efficient. I haven't seen an optimization point yet, but I haven't had much time to comb through it.

Downside off the Upgrade -
Everything is package into one EXE. That means I have to extract the ROM image to do some l33t-tastic ROM cooking. So far UniExtract, only yields and EULA text file. But again, I haven't had much time to hack at it yet. Will keep you posted on the ROM hacking.
