You're probably thinking "Eh? But Gravity's a Twitter client!" - in which case there's no need for you to grab this 'out of cycle' (to borrow Microsoft and Adobe's terms!) update for Gravity, version 2.70 (build 7208). Gravity also works pretty well as a YouTube client, letting you stay up to date with the latest videos from your subscriptions, and this new version responds to a change in the undocumented YouTube APIs. Screens and link below.

Here's the new beta in place on my Nokia E6. Shown below is the YouTube interface - essentially just new uploads from your subscriptions.

Once youve tapped on 'Watch', each video does take a few seconds to buffer and there's the caveat that there are no playback cue controls, so you can't drag the playback indicator along the timeline - it's not clear why this should be so but I'm assuming it's a Symbian in-app limitation.

You can grab the latest beta build 7208 from here, though do note that it's unashamedly beta and that strange things may (very occasionally) happen!
