my iPod worked fine up til this week. It keeps freezing and white-screening. Also, sometimes while I'm just listening to music, the brightness is all killed, and when I go to Settings, the Brightness bar is turned all the way up, but there's nothing lit up. When that happens the iPod tends to run really slow. I reset it alot, but when it's booting up with the Apple logo, it just stays there. I'm sorry if this was posted before (I searched for posts like this already too). Btw, my iPod is NOT jailbroken.
