Talk to Apple Support
When all else fails Call Apple. I know you want to get going with your new iPhone but I would wait to talk to Apple in the morning. If you activate with someone else's (your cousin) computer it will only cause you problems later. You waited all this time, a few more hours won't kill you. Good things come to those that wait.I already have iTunes selected as an exception and no i have never had an external drive connected before that i do not have now
but i came across something earlier on the Apple website saying something about the proxy settings or something,
heres the link
is this it?
