Updated via Kies tonight, and it all went without a hitch. . . . .couple of issues with App Brain/market telling me I have pending updates for Google Maps and Adobe Flash, and then throwing a tanty when it tries to install them and discovers they're already up-to-date; I guess that's what you get when you upgrade from Froyo to Froyo, and Kies thinks you have actually had Eclair.
Also, the e-mail notification icon in LauncherPro isn't updating once I've read e-mails.
Very pleased to report the speed is lovely - I turned off the ext4 lagfix on my Doc rom tonight, and it was pretty laggy. . . . .the speed difference is huge on this new rom, but time will tell!
