I've had my on an incase slider case through practically all my time I had my iphone 3g and now that I was going to put it up for sale. I noticed that in the bottom of the iphone near the charging port there is a crack! My question to you is does apple cover that? Am I screwed on selling my iphone now? It works perfectly but now I'm afraid I practically have to give it away to get rid of it What should I do?
