Yes, thank you for the thread. I get delays on both phone orientation and when opening or typing into sms apps. I never had this issue with 2.1
Using Handcent and Launcher Pro with both versions.
Today is the first time i've seriously considered rooting to have froyo without the headaches.
edit: Thought I should mention that I did a FACTORY RESET right after the OTA update. This seems to be everyone's answer to 2.2 issues. Time to think harder about 2.2 issues.
