I was wondering if anyone else has flash 10.1 working on their droid x?!! I found a download and instructions on how to get flash for 2.1 Eclair. Just follow the instructions on the link How To: Install Flash 10.1 On Android 2.1 Eclair Devices
then go on to install Skyfire beta from the Android Market.
After all goes well you should be able to load flash movies in the browser without the youtube app. Worked for me so let me know what you think.
