ok so i was using apollo im when my ipod suddenly froze. it wasnt working so i rebooted holding the power and home button, waited for the apple icon, and finally the lock screen loaded. i slid to unlock and was on the homescreen and everything was working fine. but i clicked on my music and it wouldnt let me scroll through. i tested the other apps and whenever i touched the screen nothing happened. now when i press the sleep/wake button the ipod dims on the lock screen but i can still see my background and slider. i dont kno wat to do. CAN ANYONE PLEASE HELP!!
