I finally got around to the pocket test with my Apple leather case, and I am happy to report mine doesn't pop out. I've even tried dropping the phone/case from a height of 36". I read a tip on this forum sometime ago (and I wish I could remember who it was so I could give them credit) to squeeze the corners before putting my phone in. I don't know if this is why my phone is snug or if I just got lucky. In fact, my phone is so snug and I have such a hard time taking the case off my phone, that there are creases on the back of my case where I slightly bent it, trying to remove it.
