This post is a result of over two-plus hours of research, my use of the search here and on Google, and still coming up empty. PLEASE don't flame me - I am giving what I have found for those who are in the same boat I am. 
I installed the Froyo 2.2 update on my hubby's MotoDroid and looked and looked for the Adobe Flash 10.1 update. It took me a while to find it for my device, and even longer for me to find again!
Nevertheless, I FOUND IT and wanted to post a link for everyone who keeps asking where to find it.
I used the first one, and other than being a bit newer and a bit larger, I have not tried the second one.
This is for com.adobe.flashplayer-3.apk 10.1: com.adobe.flashplayer-3.apk
THIS LINK DL'S A .txt file - I am researching this!
This is a link to Adobe Flash Player 10.1_10.1.61.68.apk : Adobe Flash Player 10.1_10.1.61.68.apk (thanks to nstallion)
Go to one of these sites using your phone's browser and download it. After it's done downloading, pull down the window and click it. It may come up saying applications like this are blocked from being installed on your device. Select SETTINGS, and check the box - then OK the warning (you can unselect it after installation).
It will install and *VOILA* You have Adobe Flash Player 10.1! I did not use APK installer but I do have it on my device. That may have helped and it never hurts!
Enjoy! BTW, I am not the person to whom you should direct questions, as I don't know much about the goings-on in my device. Everything I know, I know from here
(Thanks to all who post and ask questions and take time to research and answer them! YOU ROCK!)
Dawn - hoping this makes the Flash Player download MUCH easier to find for others!
