Hi, i have a iPod touch 2G, and i use it normally, im not rough with it. For some reason though, i notice that i have a few tiny specs of lint/dust under the bottom of the screen. Is this problem covered by my warranty? I have had it for 3 months. I notice it when im using my ipod in the light without the backlight on. They are all at the bottom so i assume the dust is getting in from the dock connector! Help?
