My wife's 2G 3.0 OS jailbroken iPhone has been acting wacky lately. If you push the sleep button on top and wait a few minutes the screen comes back on by itself. I tried a few things: made sure there were no unread messages, all unread email was cleared, restarted her iPhone... nothing worked. Her iPhone keeps waking itself up for no reason every few minutes. Also, not sure if related, but her volume is also resetting to the middle. Not ringer volume, but sound volume. She notices cause she can't here the clicking of the virtual keyboard buttons. Any clue as to what is going on?
