Once every 2 days or so i will put my touch to sleep just like always. Hours later I will go to use it and it will be completely unresponsive. I press both buttons, hold the sleep button and nothing happens, the screen stays black. The only way to get it back is to reset it by holding the home and sleep buttons at the same time. When it resets the battery is under 10% so I then have to recharge it. This is happening more and more often and is extremely frustrating because it kills the battery every time. It is a jailbroken 16gb with the a few installer apps. THANKS!
