What ME? Drop my Phone?
Ha...ha...ha... Actually I'm laughing because I was just thinking the same thing.
I really like to avoid using a case but it's so dangerous not to. That's why they're called accidents. Not one person I know including myself ever deliberately drops their phone.
Here's my solution for total protection when dropped. Its inexpensive and 100% foolproof.
I buy a small thinly padded Case Logic brand GPS Case @ Target.
It has a zipper to keep it closed. And without external or internal pockets it's barely ads to the size of the phone. Easy to remove quickly, I've got one for each phone. If I drop the phone when getting out of the car, or when my hands are full it's totally encased & protected.
It also allows me to avoid using a screen protector as well. For $10, you can't beat it.
