This is why I think it's insane when I see Bitcoin-based services built apps for iPhone first. How naive are they? It's obvious as night and day that Apple would try to ban Bitcoin apps if they try to get into payments themselves.
We should try and stop them, of course, but why risk it by making iOS your first platform, and even your only platform for a while, if you you're building an app that has a very high chance of getting banned by Apple for arbitrary self-interested reasons.
