Hello, I am an overseas student study at Australia, I bought a Macbook Pro and want to develop some iPhone software, I registered an Apple ID(so I can download the SDK), the registered address is my current address in Australia, then I login in iTune, it asked me for payment option, I filled up my credit card information, it told me the visa number has a billing address in China, but my registered address is in Australia, it wouldn't let me pass. Then I found there was an option for changing address, I changed it to China, then everything's OK, but then I realised it showed only Apps/Music/... in Chinese region, so my question is, in order to buy something in Australia region, do I have to have some payment method which has billing address in Australia? Another problem is, when I upload my iPhone software, which region does it go to? Is there anyway to just use billing address in China(to match the visa number) and everything else set to Australia? Thanks!
