I have seen a post from someone here saying they got game viewer to work on the Nokia N81 Symbian using Skyfire. As for the performance or quality though, I haven't seen anyone else comment.
As you mentioned, Android supports flash. Unfortunately the droid wasn't out when I bought my first phone, or I would otherwise have bought one. I'm too broke now.
RIM and Adobe originally announced that they were working together to bring Flash to BlackBerries in October of 2009, but this has been delayed multiple times. Last I heard was second half of 2010 with no specific date. Its almost 2011 though, and they are still supposedly working to optimize it for Blackberry hardware.
PSP is supposed to support flash, so maybe it would work. Of course, another alternative for supporters for whatever you are using would be to view the play-by-play recap over pretty much any mobile device.
