Flash is supposed to be in the 2.2 release that should be out by the end of December. I have a Epic and for Flash I use a browser called Dolphin, there is also Skyfire, and both can be found in the Market and are free applications to download.
Did this help? If so please rate this post and mark your post as answered so others can refer to it quickly for solutions.

I haven't been following the Flash issue too closely, but as I understand it, Flash 10.1 isn't officially supported on Android 2.1/Eclair. It is on 2.2/Froyo, and whenever we finally get that update, we should easily be able to install Flash from the market. I'm pretty sure I've seen it on AppBrain, so it's out there. I did come across this link -- http://www.addictivetips.com/mobile/install-flash-
On my epic 4G with Froyo, I do have Flash 10.1 Installed, but firefox mobile browser doesn't seem to have a proper plugin, nor does adobe see firefox mobile as a legitamate platform for a plugin. As for using the built in browser, it's hard to say if flash 10.1 is working because most sites I go to, automatically load a "Mobile" optimized version.
