i have an iPod mini i bought in july, it has the latest updates installed and using the iTunes 6.0.1, or whatever iTunes it was that just came out. anyway, my ipod mini has a tendency to freeze while playing music when i switch between songs. and i plugged it into my pb today using usb, and it froze itunes, and it gives the finder a hard time. i can't access the music content of it at all. any advice? please help!
