I had the same problem a couple of weeks ago, I'm glad you brought it up. Cross-fading the status bar to different backgrounds (after speaking to our developers) seems to definitely be possible in iOS7. Just consider the rest of that screens animations if you also support iOS6.
Fading the status bar color nicely is great, but is it actually possible to display the status bar controls in both white and black like the first Dribbble example?
