Ever since iOS4.0 came out (even before I installed it) my iPod Touch no longer downloads apps from the appstore. The appstore itself loads (slowly) but when I try to buy something, it just takes unbelievably long and then doesn't even ask me for my password 9/10 times. I haven't tried buying a paid app because I don't want to pay for something that I don't get.
I can still buy apps from my laptop, but it's a pain.
I'm currently in Australia, but I still use the US appstore (since that's where I live).
Any ideas what it might be?
