Can't complete installation of iOS6 on ipad2.
I went into 'settings', noticed there was a new iOS update and so installed it. After a while, the screen popped up saying 'your ipad was updated successfully. There are just a few more steps to follow, and then you're done!' and then I click continue, and it asks me to choose a wi-fi network. I click on my network, there's a tick beside it, and then it just goes to an apple page that says 'Hmm, the page you're looking for can't be found'. At the top of the page it says Apple - Page Not Found, under that http://www.apple.com and under that it says 'log in' but it's greyed out and I can't click it. I can't get to the main screen or anything, and if I power off, it just comes back to the same page.
Please help?! I am panicking now as I need to use it for work tomorrow and I can't do anything... :(
I am on an iPad 2.
