HT201263 iPhone 4 stuck in loop after downloading iOS 6.0.1

Question

I downloaded the newest version of iOS 6 to my 5 month old iPhone 4. After about an hour I noticed that the phone was in a perpetual power up/power down loop. I assumed it was part of the downloading process (although it seemed weird) so I left it for another hour. The phone never came out of the loop, and was not recognizable in iTunes or to my computer. After about 3 hours I was finally able to get the phone off by holding down the power button.
The loop that I described consists of the phone powering up to the apple logo, and powering down, repeating every 5 seconds.
I was finally able to get my computer to recognize the phone by holding down the home button while I connected it to the USB.
In iTunes, I restored the phone (1.5 hour process.) Following the restore, the phone hasn't changed, still stuck in the loop.
I have tried everything I know to do.
Any ideas?
The phone is not jailbroke. When the guys at AT&T plugged it up to their computer, the screen turned bright blue. They said the blue screen normally pops up with water damage? The phone hasn't had any damage.
