A. I have a used iPhone 4/4S HOLDER, not the mount, for Pro Clip or others if it will fit. It is in perfect working order and includes all the parts. This is the swivel model. See link below for description. I used this mount with a slim case, I cannot attest to its usability with other cases. I upgraded to an iPhone 5.
C. $30 includes shipping
F. Contact me via this thread, PM, or cell available upon request.
