I have owned several Windows Mobile devices, included the latest and greatest HTC 8925. That said, I have never been able to access real Flash with any of them. FlashLite? Yeah, but not desktop Flash... Not embedded into the browser anyway. There are workarounds to view YouTube videos (not Mobile YouTube, .3gp videos, but the real thing) I am aware of, but none released yet for viewing embedded, desktop flash.
I guess what I am getting at is... What exactly did you do on this Windows Treo to view desktop Flash sites? Oh, and to further reiterate... can't be done on a BB yet.
