Hi. Im not a real smart computer person, so please any replys, make them simple. My ipod touch shuts down after whatching about 20 minutes of video. It restarts itself and the videos wont play for a while. Any ideas? Also, when my brightness of my screen is turned to low brightness, the screen seems to flash a little. Is this normal. Just so you know, Im running a jailbroken 1.1.1. Thanks!
