I'm having big trouble with my Ipod Touch 8GB. Sometimes when I played the games (mainly bejewelled 2) every single time after download the game the screen went blank and back to main frame. It bothered me as if never happen before! and sometime when I kept a note in note pad or calendar during the process it goes back again to main frame! (which then I have to retype every single word all over again) why is that keep happening??
