Well I talked to my GF about it and here is what she said:
We are aware of the interest in purchasing iCash outside of the SEA-ANZ region. However, it would be a violation of legal terms for IAH to sell iCash in regions where we do not have the license, so it's not a matter of it being low on our priority.
If we had distribution rights to NA for any of our other game products, we would be able to distribute the icash cards there. Otherwise, I believe the safest (from fraud) and best option would be to check with some of our distribution partners (e.g. 8interactive, Epicsoft, iAm-Interactive, etc.) to see if they have distribution channels in your region.
What often happens, short of the slower route of asking gamer-friends to ship things over, will be gamers locating a source of parallel imports (which I hope everyone understands we cannot be involved in without violation of contractual agreements).
P.S. I will make the suggestion to them, though I can't guarantee if any of them will set up anything in the immediate term due to time and cost factors (if they haven't done so).
Sorry Jeony, the official word is 7-11 U. Can you get me a Big Bite while you are there
