In this weeks Developer Diaries, we take a look at the new themes and the Friends channel. This is to follow up on the themes we showed you at E3. We’ve got some new screenshots that show what the new themes will look like, as well as how current themes will appear. We also take a look at the friends channel, which is where you’ll see your friends avatars (don’t worry…the friends list as you know it is still available in the guide.) Head on over to Flickr to see more screens and the Gamerscore blog for more details.
