The screen lag is kind of driving me nuts in 2.2 and I'm thinking about going back to 2.1 for a while to see if i miss the updates in 2.2 enough to live with the homescreen lag. I've installed LauncherPro and the screen redraws are better, but still happen enough to annoy me. I'm not sure if i use flash too much, but i know i need 2.2 for it. But what about the updates to gmail, youtube, etc? Do those show in the market if I'm on 2.1? Also, I didn't root until 2.2 so I don't have a backup of my 2.1. Is there a simpler way to flash back to 2.1 without using RSD? The link I found to an image for 2.1 to flash no longer works.
