Hi all! I have just discovered that I will end up with an extra $230 this month so I would like to buy an Ipod Touch 2G 8gb. However, I've read a lot of messages here and there about dust behind the screen. This scares me a bit. I am a picky person when it comes to technology. So here are the questions: 1) Is the phenomenon very common or is it just something that happens once in a blue moon? 2) What's Apple's policy? Do they repair/change the ipod, like the they do for light leaks?
