SoftBank here in Japan disables wifi hot spot in the settings menu. Same with the camera shutter sound. I am considering getting an iPhone 5 on Apple Canada because it comes factory unlocked and my family can send it to me. I was thinking that another bonus would be that the hot spot setting wouldn't be disabled. But once I update via iTunes in Japan would that setting become disabled again? If not, how come I come I can only ENABLE that setting via a jailbreak with my current iPhone 4 in Japan? If I pickup an iPhone on Apple Canada maybe I'll have to update via iTunes Canada every time? It shouldn't matter what store I get the updates fron but it does because every time I restore from iTunes Japan after jail breaking, the hot spot setting gets disabled again.
