Chinese with the iPhone - What happened to the iPhone app? How do I use it?

I am a paid subscriber and was looking forward to manage my lesson bookmarks and such on my iphone. But seems like the only thing I can do is to listen to lessons in reverse chronological order or endlessly hitting "more" until I find a particular lesson that I want to review?

The screenshots on the itune app store does not match what's on my iPhone. Mine has ugly round buttons. What am I missing?

Thanks,

P.K.
