Hey, so my iPod Touch 2G jailbroken on 3.1.2 firware has a problem. Sometimes after I put it on sleep (just tapping the power button, not a full shutdown) and leave it for a while, it won't turn back on. Just holding the home button doesn't work, so I have to force restart it (holding the power and home buttons down). I restored my iPod about a month ago and I really don't want to again. Any suggestions?
