Adobe Press Release (June 24 2009) announcing Flash on HTC Hero: http://www.adobe.com/aboutadobe/pres...toAndroid.html ---EDIT--- What I find confusing about the above PR is that it doesn't specifically say that Flash 10 is on the shipping devices, only that Flash is on the device and that so I don't think this is Flash 10 on the HTC Hero, but some sort of 9/10 hybrid variant. In fact, this video made by an Adobe Flash developer pretty much spells it out - it's not the full Flash Player 10, just something that satisfies 80% of the content on the web (which is better than zero percent as was the case previously on Android). ---END EDIT--- I suspect it was all down to timing with the ARM build of Flash 10 (non-optimized version) either arriving too late for Fremantle or it wasn't good enough (not stable enough) and Flash 9 was the safer bet. Flash 10 will come... when it's ready.
