What about people in the US can you login? Is it just people outside the US.
I have moved from the US to Australia and bought quite a lot of apps from the US store and now it looks like I will never be able to update them again. This is very poor from Apple.
I'm in the US. Can't log onto iTunes, either. My wife and brother can log in to their accounts from the same computer/network, so it seems like it's something on Apple's end.
