Happened to me too. Picked up the phone and nothing. Not even holding down the top and bottom, plugging into iTunes, plugging into the charger, or removing the SIM card. About 30 minutes later, holding down the top and bottom brought it back to life. After a lengthy phone conversation with a product specialists, who said it was the processor backing up and shutting down, I decided to take a wait and see approach. holding open my option to get a new one. I also had the issue with the camera roll not displaying pictures, but a restore fixed that. Advice?? Should I just get a new phone? Only up to two strikes. A third will be the clincher.
