If you've not tried this yet...hold the home & power button for up to 30 seconds and see if the screen comes back with the Apple logo - if that happens, let go of the buttons and let it restart... otherwise, it's unusual to have a hardware failure coincide with an iOS upgrade... refer to qualified service personnel for diagnosis and repairs, or AppleCare+ replacement...
