I have had OG Droid since December of '09. Never had a case on it. It's been dropped numerous times. 2-3 times from 4+ feet onto concrete as I've got out of my car. All there is to show is a ~2" horizontal crack. The screen still works perfectly and you can't even tell it's there when you run your finger over it. Fast forward to the present. I'm thinking about getting a 4S. I'm wondering how strong the iPhone glass is compared to the OG Droid. Although I try to avoid dropping it, life happens sometimes. Seems like there are pictures all over this site showing an iPhone after being dropped and the screen is completely cracked and unusable. Thanks for any insight.
