I got a 5 GB Ipod and I've got it replced by apple for 3 times. This "new" 1 I just upgraded to 1.2.6 and I noticed something strange. When the ipod is completely shut down it makes clicking and cracking noises like it is still on and the ipod is accessing the HD. I have never heard this before. Any1 knows what it is? Oh this 1 is going back to apple too because it only plays for 6.5 hours on a full charge without phones.
