Does the little clip help keep a secure grip on the phone? I've seen something similar that's like a little tab that swings out from the back that can be placed between your two fingers, thus eliminating the need to keep your pinky at the bottom.
Actually, it's a clip that allows the phone to connect to a belt clip. But I rarely use it for that. Instead, I have the 'belt clips' fastened to the dash in my cars so I can just click the phone in when I'm driving, see the screen and use it for GPS, music, etc.
