This morning at the bus stop, I dropped my iPod Touch onto the ground. When I looked at it then it was okay but I noticed a few hours later that there was a strange crack across the top right of the screen so I'm assuming that was what did it - either that or the fact that it was thrown around in my pocket a bit [I'm not sure if it's a crack or a scratch, you can see it whether the iPod is on or off, but can't really "feel it" on the screen]. It doesn't impact the screen or functionality at all - everything still works, even buttons that you "touch" that are located beyond the mark. What can I do? I just bought it last week.
