Earlier quoted context omitted.
I'm also a no case person. I don't remember ever dropping my iPhones. But it is not for everyone. Once a friend took my phone to look at something and he dropped it, shattering the glass. I was more amazed that in its entirety of 3+ years, I never dropped the phone once but it slipped my friend's hand in just that few minutes. :-)
How sure are you that it was an accident?
He insisted paying for the screen replacement but I didn't let him. I got the battery and screen replaced and my iPhone is on to its 4th year. :-)
