Google has officially declared its S60 YouTube client compatible with the Nokia 5800, with the release of v2.2.9 (it was 2.2.6) on m.youtube.com (i.e. you no longer have to intercept the one offered to S60 3rd Edition phones and transfer manually - you can just go to Google's mobile site in Web on your 5800). There's also a new 'Flag' (as inappropriate) menu function, but still MIA are login/favourites/commenting - surely a version 3.x version will be needed for these? Curiously, there's no 'official' compatibility yet with the N97. Watch this space.
