Ok this may be a silly question to some, but I seriously don't know the answer, so here goes: I'm living in Canada right now (temporarily), and since my address is Canadian I had no choice but to register a Canadian iTunes account. However lots of apps and other content are only available in iTunes of other countries. I already used my credit card info for the Canadian store, am I allowed (or am I able to) to enter the same credit card info to register for another country's iTunes (for example, iTunes Japan or iTunes US), and enter some bogus information for address, if I want to buy stuff from that store?
