I just installed this upgrade, all seemed to go well and all working good.
The screen dimming issue when going to landscape is fixed.
The new key preview is nice.
I had to re-pair one Bluetooth device
Ubertwitter needed to have credentials entered again
Facebook needed to have credentials entered again
A few icons(apps) moved to different folders
Meterberry needed to have it's s/n re-entered
Meterberry v2.0.2 "reset device" feature works. Blinked a few times though?
All Outlook calendar/contact data seems to be correct.
Speed dials are intact
Browser saved URLs are intact
Boot time seems slower
but I never timed it.
Phone worked right away, no activation or anything.
Will post any updates
