According to wmpoweruser.com, someone at XDA-Developers had gotten their hands on a leaked copy of Adobe Flash Lite 3.1 for Windows Mobile. I haven’t tested this version yet, but it is said to work well with Flash sites, including YouTube. You can grab your copy of the leaked Flash Lite 3.1 by clicking here.
