Hi, I live in Australia and want to buy an iPad, I don't want to wait until late April though, if I buy an iPad on April 3rd in the states and get it shipped to Australia will it work fine? Is there any difference between the US model and the Australian model? It'll be WiFi 16GB. I imagine the "power cord" will be for an american power point, so I'd have to do something about that, but that's all I can think of. Will it still be under warranty when it leaves the country? Any thoughts?
