screw you dude. Some of us need our phones. I made the mistake in trusting that Apple could still do their jobs even with Steve Jobs gone. What a joke. Think about this. If their servers can't handle a simple registration confirmation, how the hell is iCloud supposed to manage huge data transfers????????
When the update fails it doesn't make your iPhone useless. It works just as it was working yesterday.
Can't you wait another day? Maybe just a couple of hours?
EDIT: BTW, it seems they are starting to solve the problem. It now worked for me.
