There are a good many still waiting. It's early on. I had heard rumors about a temporary stop due to some download errors with the first batch sent out end of last week. At this point, I'm thinking that might be possible as I haven't seen any updates coming across today on two forums.
If you have to ask then most likely you don't have it. But go to settings, then about phone then Software Information. Should say Firmware version 2.2 if you have it. Most likely it'll say 2.1 update1
I just got my OTA update this morning and went to the market place (Droid 1) to get the Adobe Flash 10.1 app. I haven't tried to play any games yet, but I went to m.flash.com and it loaded a game perfectly.
I just got my Froyo22D update a few minutes ago. Took about 2 mins to update.
I can't wait to start streaming some of my favorite music sites. Right off the bat, I noticed my Swype stopped working after the update.
