I like most forced the 2.2 from this website and was having the same problems of sluggishness on displays and battery problems. I cured the battery issue by loading Advanced Task Killer 2.2. It's not as simple as the original but it does kill almost all app's except for Google Services Framework and Android keyboard which are needed I guess. Like I said my battery usage went back to normal but I still had the sluggish response on screens. Two nights ago while out of town for work I recieved the OTA for FRG22D. At first I was scared cause some have had even more issues with it but I bit the bullet and let it load. All is great now. My screens aren't sluggish anymore, I didn't lose anything that I can tell so far and all applications are working without issue. I have used the Touchdown App for my email exchange server and it has never had any issues with any of the upgrades. I've also noticed something new since the upgrade, I no longer have to long onto my VPN to get my emails when tethering with PDANet on my laptop. I guess since the Touchdown App is already running with my VPN, it syncs with it and automatically syncs the two together. I'll quit gloating now since I know there is a lot of guys on here having real issues. I just figured I would post something positive to give some a little glimmer of hope.
