just to share my experience...

I flashed the new firmware (only the fiasco image, not the vanilla/emms image) using flasher-3.5, and was a bit scared that my bluetooth keyboard wouldn't work (earlier I only did OTA upgrades), but I am happy to say that it worked without much trouble (I did however have to edit the configuration file and follow the steps I had followed the last time I set it up, cf. http://talk.maemo.org/showpost.php?p...0&postcount=39).
