iPhone Apple Logo and Display Flashing

Apple iPhone was very hot and froze. I just reset it and it keeps loading up tot the Apple Logo, then flashes and resets itself. Won't let me reset or shut off. I plugged it into the Dock Connector it came with, and it wouldn't be recognized by iTunes. I reset it when it was in the dock and waited for it to cool down. I then held the power button and it started back up again.

It won't be recognized by iTunes to restore.

Any help?
