I think Apple's servers might be screwy. I tried to click "Buy" on some orbs and it is just sitting on "Connecting..." for ages. After ~5 minutes it came back with an error saying Apple's servers weren't responding. I closed the app and tried it again, and the same thing happened just after the title screen.
As an aside, having such a long timeout period is pretty dumb.
