Thought I might stir things up a bit - I managed to transfer a new libflashplayer.so across from my Motorola Atrix (from the Linux Webtop mode) onto the N900.. and it recognises it as v10.2!

Youtube and all plays along with some sample Flash 10 testing sites.

However..
Having issues with it caching the stream past the 23 second mark.

Is there anywhere that I can tweak the download memory/parameters that might be able to get around this issue?

Not sure how legal it is to post it here.. so wondering if people can help with this?
