BB Torch :: 9800 Reboots Intermittently For Nothing

My Torch is about 9 months old. I had no problems with it until about a month ago. It constantly reboots. It is not software. Sometimes when you close the slider, it goes dead and reboots. I have now seen that if the slider is open and you softly wiggle the screen part it reboots.. not always.. This tells me that it is a hardware problem. A factory fault if you ask me. My wife's Torch is 2 months old. Same problem. Also reboots for nothing. Work colleague, also a torch. Just over a year old. Same problem. Reboots 4 or 5 times a day. This is definitely not software. If you put it down too hard, or keep it in your pocket. A lot of the time it reboots...
