Perfect condition Proclip iPhone 4 mount/holder. This will NOT fit a naked iPhone 4. It's meant for the iPhone 4 + bumper case. I have tried other cases and they do work with the mount.
The picture below is of just the mount but it gives you an idea of where it mounts. I am selling both the mount and holder. They are sold from ProClip as 2 separate pieces. The holder both swivels and tilts.
