Same... and I have always had a case on my iPhones that isn't there for any serious protection.
My wife was kneeling and as she moved to get back up, her iPhone 4 slipped out of her pocket and fell about 1.5-2 feet to the ground. The back glass shattered. Apple's tech support was surprised when I told them it was the back glass as it is manufactured from the same glass used to make helicopter windshields.
I'll post a picture after I get home and have a chance to see it.
