Same problem over here. Just all of a sudden it wouldn't scroll downwards any more. I tried hard resetting, canned air, even tried to reload the OS. My computer tech was not happy about that because we had to do the enterprise actavation all over to sync me up. lol Which wasn't really even necessary because now TMO is sending me a replacement. All you'll be responsiblie for is shipping as long as there's no water damage.
