Motorola Droid 2 :: Can I Downgrade From 2.2 To 2.1.1?

I have a Motorola Droid 2 on Verizon. It is not rooted, just a basic phone with a few apps. I'm currently running Froyo 2.2 and I would like to get back to 2.1.1, or frankly any version other than 2.2. I got my phone last year in November and it was running version 2.0. Since then I have upgraded to 2.1 and 2.1.1. Around a month ago, the 2.2 update was pushed to my phone, and after reading great reviews about it, I was excited to upgrade. I allowed the update to my phone and since then I have experienced constant problems with it. Another "update" was pushed to my phone a week or so ago, but I checked the version after the update and it was still 2.2, so I'm not sure if it actually did anything, and I still have the same problems.

Since updating, my web browser freezes up regularly making it unable to use. Some of the applications I use frequently crash or freeze up (such as Pandora). The phone is much less responsive; I sometimes have to just put it down and wait for it to start responding to input again. When I try to select a text message to read, most of the time it enters a different thread than the one I selected. I'll then have to back out and try to select the text message I want to read again, and it always works the second time. The phone often misses calls; it doesn't ring or anything. I'll just get a voicemail, which is the only way I know I missed the call; no other notification or anything. It no longer plays WAV files. About half the time I try to load a YouTube video, or even launch the YouTube application, I receive a message that there is no internet connection, even though I'm using the web browser and I know I have an internet connection. Before upgrading, I almost never rebooted my phone, but now I have to rebooted multiple times a week because of the freezing and crashing of apps. Basically it has went from a smartphone, to just a phone. I am so frustrated. If I can't downgrade, I think I'm just going to have to get a different phone. I have found posts on how to downgrade other phones from 2.2 to 2.1, but I'm not sure if they work on the Motorola Droid 2, and I don't want to risk being completely without a phone, since I use it for work and personal use. The other guides I have found for the downgrade seem to specify they are for phones other than the Motorola Droid 2.
