It's possible your app got rejected entirely because you didn't provide a launch image (formerly known as Default.png).

I'd echo the concern that the status bar should be visible in your app.

Another polish item: rows in the detail view controller get a selection highlight when you tap them, but don't do anything.

Apple also looks to see if there's a way to provide user feedback within the app, so you might want to add something for that.
