For those curious as to what I mean, ask yourselves-- didn't you grow up with a certain game related to money and property trading? Monopoly! What is those properties were actually representative of something else like a trade of value between another "player"?
Do you remember another little game called DIGIMON where you traded monsters? What if those monsters were just a representation of value? Do you remember being able to create said monster by insterting a CD into your drive and having an algorithm create one from the checksum/hash? Who's to stop you from creating monopoly money from a QR code?
Furthermore, with the Apple Game Center giving you all the tools (free API) for multiplayer games, what's to stop one talented coder from making an 'exchange game', or basically forex simulator? Desperate users could even buy fake bux (iTunes credits) in-app at a huge markup (30%+ for iTunes fees + risk of chargeback).
No, I'm not saying I'm making this right now (why would I ever admit that?), what I'm asking is, why isn't this avenue being tried by everyone else? Is the threat of eventually finding out and bashing it down too great?

The best fixes I can see for the Apple Bitcoin ban is:
1) Android
2) Even better when it comes out: Ubuntu Phone
3) Jailbreak
Well, that's not really a fix is it, it's more of a list of alternatives. (I use Android myself for that very reason!)
