The Adobe open screen project does list Arm and Nokia as partners in a project to bring Flash 10.1 to mobile devices, http://www.openscreenproject.org/par..._partners.html

Also there is a contact email of the project leader at Adobe, it might be worth an email to them, after all they did showcase flash 10 on a N900 over 6 months ago, it would be rather embarrassing for them to not release Flash 10 for a phone they showcased it on.
