The iPhone 3G was dropped from less than two feet on garage concrete floor and cracked an inner screen, not the screen on very top. It still works fine. This was the most 'soft' drop of a cell phone. I have dropped Treo's from much higher and not broken them. Have two iphone's 3G in family so now paranoid. My thoughts on durability have vanished. It is a horizontal crack in portrait view. Will be buying two protective cases today. Where do I take it for service. Purchased at AT&T. Idea of cost of screen repair.
