Yesterday I took my first generation iPad with me on a bike ride, and on my way home it started raining. It rained so hard that during the ten minutes it took for me to get home the backpack got soaked, but the black cover (the one that covers the iPad entirely and came with the first generation) was just a little damp. At first I didn't think it was damp at all, I just noticed that when I had taken the iPad out of the cover. To my horror when I started the iPad it had areas on the screen that were lighter than the rest. I turned the iPad off but it kept restarting itself (btw the touch screen and everything else including the wi-fi worked perfectly at this point), so I just lay it there for the night. About sixteen hours later I started it again and now there were larger lighter areas than before and it flickered sometimes when I used the touch screen. I let it rest some more and then four hours later it wouldn't start at all. So I'm pretty confused? It was hardly damp, and why did it take so long for it to stop working? Basically: what is the likely cause of this malfunction? Which component might have been involved etc.?
