i just dropped my iphone 3g during lunch today and the screen cracked. There's parts of the screen where the glass is sharp and falling off, and there are parts of the screen where the cracks are below the surface and the top glass is still smooth. for reference, bought the iphone in july 08, it has no applecare. I walked by the apple store after lunch and they told me it they could give me a replacement for $199. On another note, my friend has an iphone 3g that is broke from water damage. is it possible to use his screen and put it on my phone?? or did the water damage ruin his screen too?
